5.1(3)N1(1)	This command was introduced.

Usage Guidelines

This command does not require a license.

Examples

This example shows how to configure the DSCP value of the packets in the ESRSPAN traffic:

switch# configure terminal

switch(config)# monitor session 1 type erspan-source

switch(config-erspan-src)# ip dscp 10

switch(config-erspan-src)#

Related Commands

Command	Description
ip prec	Configures the IP precedence value of the ERSPAN traffic.
ip ttl	Configures the IP time-to-live (TTL) value of the ERSPAN traffic.
monitor-session	Enters the monitor configuration mode for configuring an ERSPAN session for analyzing traffic between ports.

ip prec (ERSPAN)

To configure the IP precedence value of the packets in the Encapsulated Remote Switched Port Analyzer (ERSPAN) traffic, use the ip prec command.

ip ttl	Configures the differentiated dervices code point (DSCP) value of the ERSPAN traffic.
monitor-session	Enters the monitor configuration mode for configuring an ERSPAN session for analyzing traffic between ports.

ip ttl (ERSPAN)

To configure the IP time-to-live (TTL) value of the Encapsulated Remote Switched Port Analyzer (ERSPAN) traffic, use the ip ttl command. To revert to the default configuration, use the no form of this command.

ip ttl ttl_value

no ip ttl ttl_value

Syntax Description

ttl_value

IP TTL value of the ERSPAN traffic. The range is from 1 to 255.

Release	Modification
5.1(3)N1(1)	This command was introduced.

Usage Guidelines

This command does not require a license.

Examples

This example shows how to configure the IP TTL value of the ESRSPAN source:

switch# configure terminal

switch(config)# monitor session 1 type erspan-source

switch(config-erspan-src)# ip ttl 30

switch(config-erspan-src)#

This example shows how to remove the IP TTL value from the ESRSPAN source:

switch# configure terminal

switch(config)# monitor session 1 type erspan-source

switch(config-erspan-src)# no ip ttl 30

switch(config-erspan-src)#
