Find What Port Number a Mac Address Is On Cisco IOS

If you know the full Mac address, you can perform the following:

show mac address-table address 6476.7A98.1818

If you know just part of the Mac address (where 1818 is the last 4 digits of the Mac):

show mac address-table | include 1818

Change your interface, if needed:

enable

configure  terminal

interface GigabitEthernet0/1
 description MPLS
 ip address 10.162.131.54 255.255.255.248
 duplex full
 speed 100

Be sure that your link speed is set correctly. Sometimes auto speed doesn't work right.

And change your gateway/bgp-neighbor, if needed:

router bgp 65000
 no synchronization
 bgp log-neighbor-changes
 redistribute connected
 redistribute ospf 30
 neighbor 10.162.30.1 remote-as 65006
 neighbor 10.162.131.49 remote-as 1
 no auto-summary

And remember to save your running config as your startup config:

copy  running-config startup-config

You can show your routes by:

show ip route
