Configuration Example for Catena—Transparent Mode PACL
This example shows how to configure Catena in transparent mode:
switch# configure terminal
switch(config)# feature catena
switch(config)# catena port-group pg1
switch(config-port-group)# interface Eth 1/1
switch(config-pg-node)# catena port-group pg2
switch(config-port-group)# interface Eth 1/2
switch(config-pg-node)# catena port-group pg3
switch(config-port-group)# interface Eth 1/3
switch(config-pg-node)# catena port-group pg4
switch(config-port-group)# interface Eth 1/4
switch(config-pg-node)# catena port-acl acl1
switch(config-port-acl)# 10 permit ip 192.0.2.1/24 any
switch(config-port-acl)# 20 deny ip 198.51.100.1/24 any
switch(config-port-acl)# catena ins_1
switch(config-catena-instance)# chain 10
switch(config-catena)# 10 access-list acl1 ingress-port-group pg1 egress port-group pg2
