Maximum MTU size on Fastethernet interface.

[raju]

We have a RAS server (3745) with E1 line and the Fastethernet 0/0 is connected with Internal LAN .When dial-in user's increases more than 20 (concurrent), RAS server start sending syslog messages that MTU size on Fastethernet 0/0 exceeded . Can I increase the MTU size on Fastethernet interface and if so , What is the maximum size FE supports and since I want to try with maximum value?.

Thanks

Can you paste the Syslog message ? The max size on FE should be no more than 1500 bytes and thats the default value!! You can only set to something less than 1500.
