Leased line frequent disconnecting in router Ethernet port.

[amitpanwar]

- 90 Mb MTNL leased line is frequently disconnect  in router ethernet port in 1 or 2 hrs.

- Then start working if we physically remove and refix cable.

- Other 90 Mb Railtel leased line is working fine on same port.

- But same line is working fine when connected with Laptop with out any issue.

- Tried ethernet port swap in router and in l2 switch provided by Exchange.

what router is this ? and what IOS running ?

Can you post -  show interface gi 0/3  ( see any Drops here ?)  what L2 Switch ? do you have acces - see any Logs ?

what you see Logs on the router when you lost connection before remove cable and plug the cable ?

Hello,

hard to tell. Is the rate limiting mandatory ? You might want to try traffic shaping instead (if your IOS and router supports this).

Remove the lines:

rate-limit input access-group 10 20480000 20480 20480 conform-action transmit exceed-action drop
rate-limit output access-group 10 20480000 20480 20480 conform-action transmit exceed-action drop

from the interface, and add the below to your configuration (the exact syntax on your device might differ):

policy-map SHAPE_90

class class-default

shape average 90000000

interface GigabitEthernet0/3

service-policy output SHAPE_90
