User EXEC Mode
When you log in to the Cisco DSLAM, you are in user EXEC, or simply EXEC, command mode. The EXEC mode commands available at the user level are a subset of those available at the privileged level. The user EXEC mode commands allow you to connect to remote switches, change terminal settings on a temporary basis, perform basic tests, and list system information.

The user EXEC mode prompt consists of the DSLAM host name followed by the angle bracket (>):

Frodo>or

DSLAM>The default host name is DSLAM, unless it has been changed through use of the host name global configuration command.

Privileged EXEC Mode
The privileged EXEC mode command set includes all user EXEC mode commands and the configure command, through which you can access global configuration mode and the remaining configuration submodes. Privileged EXEC mode also includes high-level testing commands, such as debug, and commands that display potentially secure information.

To enter or exit privileged EXEC mode, follow these steps:

Command Task
Step 1 DSLAM> enable



Password:password

Enter privileged EXEC mode from EXECmode.1
Step 2 DSLAM# Enter privileged EXEC commands.
Step 3 DSLAM# disable



DSLAM> Exit privileged EXEC mode and return to EXEC mode.2
1The prompt changes to the DSLAM host name followed by the pound sign (#).
2The prompt changes back to the DSLAM host name followed by the angle bracket (>).

The system administrator uses the enable password global configuration command to set the password, which is case sensitive. If an enable password was not set, you can access privileged EXEC mode only from the console.

ROM Monitor Mode
ROM monitor mode provides access to a basic system kernel, from which you can boot the Cisco DSLAM or perform diagnostic tests. The system can enter ROM mode automatically if the Cisco DSLAM does not find a valid system image, or if the configuration file is corrupted. The ROM monitor prompt is rommon x> without the DSLAM host name. The x represents the number of commands entered into the prompt.

You can also enter ROM monitor mode by interrupting the boot sequence with the Break key during loading.

To return to EXEC mode from ROM monitor mode, use the cont command:

rommon 1> cont

Using Context-Sensitive Help
The user interface provides context-sensitive help in all modes. This section describes how to configure and display context-sensitive help.

Configuring Help for Terminal Sessions
The following commands configure full help.

Command Task
DSLAM# terminal full-help

In privileged EXEC mode, configure the current terminal session to receive help for the full set of user-level commands.
DSLAM(config-line)# full-help

In line configuration mode, configure a specific line to allow users without privileged access to obtain full help.


Displaying Context-Sensitive Help
To get help specific to a command mode, a command, a keyword, or an argument, perform one of these tasks:

Command Task
help

Obtain a brief description of the help system in any command mode.
abbreviated-command-entry?

Obtain a list of commands that begin with a particular character string.
abbreviated-command-entry

Complete a partial command name.
?

List all commands available for a particular command mode.
command ?

List the associated keywords of a command.
command keyword ?

List the associated arguments of a keyword.


To view a list of commands that begin with a particular character sequence, type those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.

In this example, the system displays the possible commands in privileged EXEC mode that begin with “co.”

DSLAM# co?



configure connect copyThis form helps you determine the minimum subset that you can use to abbreviate a command.

Command Syntax Help
To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space before the ?. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.

This example demonstrates the use of command syntax help to complete the access-list command. Entering the question mark (?) displays the allowed arguments:

DSLAM(config)# access-list ?



<1-99> IP standard access list

<100-199> IP extended access listEnter the access list number, 99, followed by a question mark (?) to display the allowed keywords:

DSLAM(config)# access-list 99 ?



deny Specify packets to reject

permit Specify packets to forwardEnter the deny argument followed by a question mark (?) to display the next argument (host name or IP address) and two keywords:

DSLAM(config)# access-list 99 deny ?



Hostname or A.B.C.D Address to match

any Any source host

host A single host addressEnter the IP address followed by a question mark (?) to display a final (optional) argument. The indicates that you can press Return to execute the command:

DSLAM(config)# access-list 99 deny 131.108.134.0 ?



A.B.C.D Wildcard bits



DSLAM(config)#

The system adds an entry to access list 99 that denies access to all hosts on subnet 131.108.134.0.

Checking Command Syntax
The user interface provides an error indicator (^) that appears in the command string in which you have entered an incorrect or incomplete command, keyword, or argument.

This example shows a command entry that is correct up to the last element:

DSLAM# clock set 13:04:30 28 apr 98



^

% Invalid input detected at ‘^’ marker.The caret symbol (^) and help response indicate the location in which the error occurs. To list the correct syntax, re-enter the command, substituting a question mark (?) where the error occurred:

DSLAM# clock set 13:32:00 23 February ?



<1993-2035> Year

DSLAM# clock set 13:32:00 23 February

Enter the year, using the correct syntax, and press Enter to execute the command:

DSLAM# clock set 13:32:00 23 February 1993

Using the Command History Features
The user interface provides a history or record of commands you enter. You can use the command history feature for recalling long or complex commands or entries, including access lists. With the command history feature, you can complete the tasks in the following sections:

Setting the Command History Buffer Size
Recalling Commands
Disabling the Command History Feature
Setting the Command History Buffer Size
By default, the system records ten command lines in its history buffer. Use the following commands to set the number of command lines the system records:

Command Task
DSLAM# terminal history [size

number-of-lines] In privileged EXEC mode, enable the command history feature for the current terminal session.
DSLAM(config-line)# history

[size number-of-lines] In line configuration mode, enable the command history feature for a specific line.


Recalling Commands
To recall commands from the history buffer, perform one of these tasks:

Key Sequence/Command Task
Press Ctrl-P or the Up Arrow key.1 Recall commands in the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands.
Press Ctrl-N or the Down Arrow key.1 Return to more recent commands in the history buffer after recalling commands with Ctrl-P or the Up Arrow key. Repeat the key sequence to recall successively more recent commands.
DSLAM> show

history

While in EXEC mode, list the last several commands you have just entered.
1The arrow keys function only on ANSI-compatible terminals such as VT100s.

Disabling the Command History Feature
The command history feature is automatically enabled. Use the following commands to disable it:

Command Task
DSLAM> terminal no

history

In EXEC mode, disable the command history feature for the current terminal session.
DSLAM(config-line)

# no history In line configuration mode, configure the line to disable the command history feature.

Enabling Enhanced Editing Mode
Although the current software release enables the enhanced editing mode by default, you can disable it and revert to the editing mode of previous software releases. Use the following commands to re-enable the enhanced editing mode:

Command Task
DSLAM> terminal
editing
In EXEC mode, enable the enhanced editing features for the current terminal session.
DSLAM(config-line)
# editing
In line configuration mode, enable the enhanced editing features for a specific line.


Moving Around on the Command Line
Use these keystrokes to move the cursor around on the command line for corrections or changes:

Keystrokes Task
1The arrow keys function only on ANSI-compatible terminals such as VT100s.

Completing a Partial Command Name
If you cannot remember a complete command name, you can use Tab to allow the system to complete a partial entry:

Keystrokes Task


If your keyboard does not have Tab, press Ctrl-I instead.

In this example, when you enter the letters conf and press Tab, the system provides the complete command:

DSLAM# conf

DSLAM# configure
If you enter an ambiguous set of characters, the system generates an error message. To display the list of legal commands beginning with the specified string, enter a question mark (?) after you see the error message. See the “Using Word Help” section.

Pasting in Buffer Entries
The system provides a buffer that contains the last ten items you deleted. You can recall these items and paste them in the command line by using these keystrokes:

Keystrokes Task


The buffer contains only the last ten items you have deleted or cut. If you press Esc Y more than 10 times, you cycle back to the first buffer entry.

Editing Command Lines that Wrap
The new editing command set provides a wraparound feature for commands that extend beyond a single line on the screen. When the cursor reaches the right margin, the command line shifts 10 spaces to the left. You cannot see the first 10 characters of the line, but you can scroll back and check the syntax at the beginning of the command. To scroll back, use these keystrokes:

Keystrokes Task
1The arrow keys function only on ANSI-compatible terminals such as VT100s.

In the following example, the access-list command entry extends beyond one line. When the cursor reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. The dollar sign ($) indicates that the line has been scrolled to the left. Each time the cursor reaches the end of the line, the line is again shifted ten spaces to the left.

DSLAM(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1

DSLAM(config)# $ 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.25

DSLAM(config)# $t tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq

DSLAM(config)# $108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq 45
When you complete the entry, press Ctrl-A to check the complete syntax before pressing Return to execute the command. The dollar sign ($) appears at the end of the line to indicate that the line has scrolled to the right:

DSLAM(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1$
The Cisco DSLAM default is a terminal screen that is 80 columns wide. If you have a width other than that, use the terminal width command to provide the correct width.

Use line wrapping together with the command history feature to recall and modify previous complex command entries.

Deleting Entries
Use any of these keystrokes to delete command entries if you make a mistake or change your mind:

Keystrokes Task


Scrolling Down a Line or a Screen
When you use the help facility to list the commands available in a particular mode, the list is often longer than the terminal screen can display. In such cases, a More prompt appears at the bottom of the screen. To respond to the More prompt, use these keystrokes:

Keystrokes Task


Redisplaying the Current Command Line
If you enter a command and a message appears on your screen, you can easily recall your current command line entry. To do so, use these keystrokes:

Keystrokes Task


Transposing Mistyped Characters
If you have mistyped a command entry, you can transpose the mistyped characters by using these keystrokes:

Keystrokes Task


Controlling Capitalization
You can capitalize or lowercase words or capitalize a set of letters with these keystrokes:

Keystrokes Task


Designating a Keystroke as a Command Entry
To use a particular keystroke as an executable command, insert a system code:


Keystrokes Task


Disabling Enhanced Editing Mode
To disable enhanced editing mode and revert to the editing mode, use this command in privileged EXEC mode:

Command Task
DSLAM# terminal no
editing
Disable the enhanced editing features for the local line.


If you have prebuilt scripts that do not interact well when enhanced editing is enabled, you can disable enhanced editing mode. To re-enable enhanced editing mode, use the terminal editing command.

Ending a Session
After you use the setup command or another configuration command, exit the Cisco DSLAM and quit the session.

To end a session, use this EXEC command:

Command Task
DSLAM> quit
End the session.

01. Introduction

This page will tak about how to make QUEUE TREE in RouterOS that also running
Web-Proxy and Masquerading. Several topics in forum say it's impossible to do.

In version 2.9.x, we can not know which traffic is HIT and which traffic is MISS
from web-proxy. Several people want to make a configuration, to let cache data in
proxy (HIT traffic) deliver in maximum possible speed. In other word, if we already
have the requested data, those process will not queued.

In ver 3.0 we can do this, using TOS header modification in web-proxy feature.
We can set any TOS value for the HIT traffic, and make it as parameter in mangle.


02. Basic Setup
First, let's set the basic setting first. I'm using a machine with 2 network
interface:

---------------------------------------------------------------------------------
admin@instaler] > in pr
# NAME TYPE RX-RATE TX-RATE MTU
0 R public ether 0 0 1500
1 R lan wlan 0 0 1500
---------------------------------------------------------------------------------

And this is the IP Address for each interface:

---------------------------------------------------------------------------------
[admin@instaler] > ip ad pr
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 192.168.0.217/24 192.168.0.0 192.168.0.255 public
1 172.21.1.1/24 172.21.1.0 172.21.1.255 lan
---------------------------------------------------------------------------------

Don't forget to set the transparant web-proxy. We set cache-hit-dscp: 4.

---------------------------------------------------------------------------------
[admin@instaler] > ip proxy pr
enabled: yes
src-address: 0.0.0.0
port: 3128
parent-proxy: 0.0.0.0
parent-proxy-port: 0
cache-drive: system
cache-administrator: "webmaster"
max-cache-size: none
cache-on-disk: yes
maximal-client-connections: 600
maximal-server-connections: 600
max-fresh-time: 3d
serialize-connections: yes
cache-hit-dscp: 4
---------------------------------------------------------------------------------


03. Firewall NAT

Make 2 NAT rules, 1 for Masquerading, and the other for redirecting transparant proxy.

---------------------------------------------------------------------------------
[admin@instaler] ip firewall nat> pr
Flags: X - disabled, I - invalid, D - dynamic
0 chain=srcnat out-interface=public
src-address=172.21.1.0/24 action=masquerade
1 chain=dstnat in-interface=lan src-address=172.21.1.0/24
protocol=tcp dst-port=80 action=redirect to-ports=3128


04. Mangle Setup

And now is the most important part in this case.
---------------------------------------------------------------------------------
If we want to make HIT traffic from web proxy not queued, we have to make a mangle
to handle this traffic. Put this rule on the beginning of the mangle, as it will
check first.

---------------------------------------------------------------------------------
[admin@instaler] > ip firewall mangle print
Flags: X - disabled, I - invalid, D - dynamic
0 ;;; HIT TRAFFIC FROM PROXY
chain=output out-interface=lan
dscp=4 action=mark-packet
new-packet-mark=proxy-hit passthrough=no
---------------------------------------------------------------------------------

As we will make Queue for uplink and downlink traffic, we need 2 packet-mark. In this
example, we use "test-up" for uplink traffic, and "test-down" for downlink traffic.

For uplink traffic, it's quite simple. We need only one rule, using SRC-ADDRESS and
IN-INTERFACE parameters, and using PREROUTING chain. Rule number #1. But for downlink,
we have to make sevaral rules. As we use masquerading, we need Connection Mark,
named as "test-conn". Rule no #2. Then we have to make 2 more rules. First rule is
for non-HTTP connection / direct connection. We use chain forward, as the data traveling
through the router. Rule no #3.

The second rule is for data coming from web-proxy to the client (MISS traffic).
We use OUTPUT chain, as the data coming from internal process in the router itself.
Rule no #4.

For both rules (no #3 and #4) we named it "test-down".

Please be aware, we use passthrough only for connection mark (rule no #2).

---------------------------------------------------------------------------------
[admin@instaler] > ip firewall mangle print
Flags: X - disabled, I - invalid, D - dynamic
1 ;;; UP TRAFFIC
chain=prerouting in-interface=lan
src-address=172.21.1.0/24 action=mark-packet
new-packet-mark=test-up passthrough=no

2 ;;; CONN-MARK
chain=forward src-address=172.21.1.0/24
action=mark-connection
new-connection-mark=test-conn passthrough=yes

3 ;;; DOWN-DIRECT CONNECTION
chain=forward in-interface=public
connection-mark=test-conn action=mark-packet
new-packet-mark=test-down passthrough=no

4 ;;; DOWN-VIA PROXY
chain=output out-interface=lan
dst-address=172.21.1.0/24 action=mark-packet
new-packet-mark=test-down passthrough=no
---------------------------------------------------------------------------------

05. Queue Tree Setup

And now, the queue tree setting. We need one rule for downlink and one rule for
uplink. Be careful when choosing the parent. for downlink traffic, we use parent
"lan", the interface name for local network. And for uplink, we are using parent
"global-in".

---------------------------------------------------------------------------------
[admin@instaler] > queue tree pr
Flags: X - disabled, I - invalid
0 name="downstream" parent=lan packet-mark=test-down
limit-at=32000 queue=default priority=8
max-limit=32000 burst-limit=0
burst-threshold=0 burst-time=0s

1 name="upstream" parent=global-in
packet-mark=test-up limit-at=32000
queue=default priority=8
max-limit=32000 burst-limit=0
burst-threshold=0 burst-time=0s
---------------------------------------------------------------------------------

You can use those mangle also with PCQ.
