Unanswered Question
Feb 13th, 2007

Hi All,

I am having an issue with VLAN intercommunication.


Switch Model: 6509

Vlan 100

Server2 (Destination)

Switch Model: 6509

VLAN 200

The problem is I couldn't ping the server2 from serve1 for some time. After few minutes its start pinging...like this the connectivity is losing intermittently...am afraid why its happening.

Can some one shed a light on this to get rid off.

Thanks in Adv

I have this problem too.

Can you paste your configuration? Did you check the port speed / duplex setting? Did you try another port or cable?

No enough information to determine the cause.

You have to make sure the switchport settings match the hardcoded port speeds of your servers , they cant be left as auto .
