Chapter 42 Troubleshooting Using Ping
This example is one possible configuration:
switch# configure terminal
switch(config)# access list 101 permit ip any any
switch(config)# class-map match-any ping-class
switch(config-cmap)# match access-group 101
switch(config-cmap)# exit
switch(config)# policy-map ping-policy
switch(config-pmap)# class ping-class
switch(config-pmap-c)# police 1000000
switch(config-pmap-c)# exit
switch(config-pmap)# exit
switch(config)# int fa0/1
switch(config-if)# service-policy input ping-policy
switch(config-if)# switchport access vlan 2
switch(config-if)# no shut
switch(config-if)# exit
switch(config)# int vlan 2
switch(config-if)# ip address 192.168.1.1 255.255.255.0
switch(config-if)# end
switch# ping 192.168.1.2
Metro IP Access Image
When your switch is running the metro IP access image, you can use any of these methods:
• Apply a Layer 3 service policy to a UNI or ENI.
• Enable IP routing globally and ping from a switch virtual interface (SVI).
• Enable IP routing and ping from a routed port.
For a sample configuration of how to add a Layer 3 service policy to a UNI or ENI, see the “All Sof twa re
Vers io ns ” section.
For examples using IP routing and pinging from an SVI or a routed port, see the next sections.

IP Routing and SVI

IP routing is only supported when the switch is running the metro IP access image.
You can use this configuration to enable IP routing and enable pings from an SVI to a host connected to
a UNI or ENI.
Switch# configure terminal
Switch(config)# ip routing
Switch(config)# int fa0/1
Switch(config-if)# switchport access vlan 2
Switch(config-if)# no shutdown
Switch(config-if)# int vlan 2
Switch(config-if)# ip address 192.168.1.1 255.255.255.0
Switch(config-if)# end
Switch# ping 192.168.1.2
With this configuration, a host with an IP address of 192.168.1.2 can be pinged from the switch.
