Feedback Target Based Commands

This chapter describes the SEFOS target based commands.


24.1 SEFOS Target Based Commands

The list of SEFOS target based commands are as follows:

24.1.1 monitor session

Enables port-mirroring in the switch. The no form of the command disables port mirroring in the switch.


monitor session [session_number 1-1] {destination interface interface-type interface-id | source interface interface-type interface-id [{rx | tx | both}]}


no monitor session [session_number:1] [{source interface interface-type interface-id |destination interface interface-type interface-id}]


Syntax Description

session_number 1-1 - Specifies the session number identified with the session.

destination interface - Specifies the destination interface or the mirror-to port. Valid interfaces are physical ports. There can only be one mirror-to port per switch.

source interface - Specifies the interface for the traffic that is to be mirrored. Valid interfaces include physical ports.

rx - Received traffic is mirrored.

tx - Transmitted traffic is mirrored.

both - Specifies the traffic direction to monitor. If the traffic direction is not specified, both transmitted and received traffic is mirrored.

Mode

Global Configuration

Defaults

Port mirroring is disabled.

Example

SEFOS(config)# monitor session source interface extreme-ethernet 0/1

SEFOS(config)# monitor session 1 destination interface ex 0/4

Notes

A port that is a member of a port-channel cannot be a mirror-to port.


Related Commands

24.1.2 speed

Sets the speed of the interface. The no form of the command sets the speed of the interface to its default value.


speed {1000 | 10000}


no speed


Syntax Description

1000 - Port runs at 1000 Mbps,

10000 - Port runs at 10000 Mbps,

Mode

Interface Configuration

Defaults

Automatic.

Example

SEFOS(config-if)# speed 1000

Notes

The Ethernet port speed can be configured to 1000 Mbps or 10000 Mbps. If the Ethernet port can not be configured to the desired speed, an information mesage is displayed similar to the following:

This speed is not supported by hardware.

24.1.3 storm-control

Sets the storm control rate for broadcast, multicast and DLF packets. The no form of the command sets storm control rate for broadcast, multicast, and DLF packets to the default value.


storm-control {broadcast | multicast | dlf} level Mbps_1-10000


no storm-control {broadcast | multicast | dlf} level}


Syntax Description

broadcast - Broadcast packets.

multicast - Multicast packets.

dlf - Unicast packets.

level - Storm-control suppression level as a total number of bits per second. This value ranges between 1 and 10000 Megabits per second.

Mode

Interface Configuration

Defaults

Broadcast, multicast, and DLF storm control are disabled.

Example

SEFOS(config-if)# storm-control broadcast level 1000

Notes

Storm control is supported only on physical interfaces.


Related Commands

24.1.4 rate-limit-output

Enables the rate limiting and burst size rate limiting by configuring the egress packet rate of an interface. The no form of the command disables the rate limiting and burst size rate limiting on an egress port.


rate-limit-output [packet-rate Mbps_1-10000] [burst-size KB_1-128]


no rate-limit-output


Syntax Description

packet-rate - Packet rate Megabits per second. This value ranges between 1 and 10000 Megabits per second.

burst-size - Burst size in Kilobits per second. This value ranges between 1 and 128 Kilobits per second.

Mode

Interface Configuration

Defaults

packet-rate - 0

burst-size - 0

Example

SEFOS(config-if)# rate-limit output packet-rate 64 burst-size 32


24.1.5 show port-monitoring

Displays port-monitoring information.


show port-monitoring


Mode

Privileged EXEC

Example

SEFOS# show port-monitoring

Port Monitoring is enabled

Monitor Port : Ex0/4

Port Ingress-Monitoring Egress-Monitoring

Ex0/1 Enabled Enabled

Ex0/2 Enabled Enabled

Ex0/3 Disabled Disabled

Ex0/4 Disabled Disabled

Ex0/5 Disabled Disabled

Ex0/6 Disabled Disabled

Ex0/7 Disabled Disabled

Ex0/8 Disabled Disabled

Ex0/13 Disabled Disabled

Ex0/14 Disabled Disabled

Ex0/15 Disabled Disabled

Ex0/16 Disabled Disabled

Ex0/17 Disabled Disabled


Related Commands

24.1.6 show monitor

Displays port-monitoring information. This command operates similar to that of the command show port-monitoring.


show monitor [session 1-10] [detail]


Syntax Description

session - Session number. This value ranges between 1 and 10.

detail - Detailed information regarding the session.

Mode

Privileged EXEC

Example

SEFOS# show monitor

Port Monitoring is enabled

Monitor Port : Ex0/2

Port Ingress-Monitoring Egress-Monitoring

Ex0/1 Disabled Disabled

Ex0/2 Enabled Enabled

Ex0/3 Disabled Disabled

Ex0/4 Disabled Disabled

Ex0/5 Disabled Disabled

Ex0/6 Disabled Disabled

24.1.7 mac-address-table aging-time

Sets the maximum age of a dynamically learned entry in the MAC address table. The no form of the command sets the maximum age of an entry in the MAC address table to its default value.


mac-address-table aging-time seconds_10-1000000


no mac-address-table aging-time


Mode

Global Configuration

Defaults

300

Example

SEFOS(config)# mac-address-table aging-time 100

Notes

If traffic on an interface is not very frequent, the aging time must be increased to record the dynamic entries for a longer time. Increasing the time can reduce the possibility of flooding.
