Troubleshooting IP Routing
The show ip config command displays IP configuration on the switch:
-> show ip config
IP directed-broadcast = ON,
IP default TTL
There are user-configurable parameters that can be changed as per requirement. The vlan mtu-ip
command sets the MTU (Maximum Transmission Unit) size for a VLAN.
-> vlan 110 mtu-ip 1500
The show ip interface command displays statistics of a particular IP interface.
-> show ip interface vlan 110
vlan 110

The show ip router database command displays a list of all routes (static and dynamic) that exist in the IP
router database. This database serves as a central repository where routes are first processed for redistribu-
tion and where duplicate routes are compared to determine the best route to use. If a route does not appear
in the IP router database list, then the switch does not know about it. In the case of dynamically learned
routes, this could indicate that the route was never received by the switch.
