Configuration Example for Truncated ERSPAN
This example shows how to configure truncated ERSPAN:
switch# configure terminal
switch(config)# monitor session 1 type erspan-source
switch(config-erspan-src)# mtu 64
switch(config-mon-erspan-src)# exit
switch(config)# copy running-config startup config
Configuration Example for an ERSPAN Destination Session
The following example shows how to configure an ERSPAN destination session:
switch# config t
switch(config)# interface e14/29
switch(config-if)# no shut
switch(config-if)# switchport
switch(config-if)# switchport monitor
switch(config-if)# exit
switch(config)# monitor session 2 type erspan-destination
switch(config-erspan-dst)# source ip 9.1.1.2
switch(config-erspan-dst)# destination interface e14/29
switch(config-erspan-dst)# erspan-id 1
switch(config-erspan-dst)# vrf default
switch(config-erspan-dst)# no shut
switch(config-erspan-dst)# exit
switch(config)# show monitor session 2
Configuration Example for an ERSPAN ACL
This example shows how to configure an ERSPAN ACL:
switch# configure terminal
switch(config)# ip access-list match_11_pkts
switch(config-acl)# permit ip 11.0.0.0 0.255.255.255 any
switch(config-acl)# exit
switch(config)# ip access-list match_12_pkts
switch(config-acl)# permit ip 12.0.0.0 0.255.255.255 any
switch(config-acl)# exit
switch(config)# vlan access-map erspan_filter 5
switch(config-access-map)# match ip address match_11_pkts
switch(config-access-map)# action forward
switch(config-access-map)# exit
switch(config)# vlan access-map erspan_filter 10
switch(config-access-map)# match ip address match_12_pkts
switch(config-access-map)# action forward
switch(config-access-map)# exit
switch(config)# monitor session 1 type erspan-source
switch(config-erspan-src)# filter access_group erspan_filter
Configuration Example for an ERSPAN SPAN-on-Drop Session
This example shows how to configure an ERSPAN SPAN-on-Drop session:
switch# configure terminal
switch(config) # monitor session 47 type span-on-drop-erspan
switch(config-span-on-drop-erspan) # description span-on-drop-erspan-session_47
switch(config-span-on-drop-erspan) # source interface ethernet 1/3
switch(config-span-on-drop-erspan) # destination ip 10.1.1.1
