Managment VLAN issues

[michael4702]

Hi,

I have two 6500 cats sitting as the core of my network, linked by a 3 gig ether channel. These are working fine.

I am introducing two new 6500's to my network to create a square backbone. But at present I am using these two new 6500's as simple dumb edge switches. They hang off my second ORIGINAL 6500 via a 4 gig ether channel in a daisy chain formation. Just as if they were edge devises. They seem to work fine, trunking VLAN information etc.

My problem is I can not ping or telnet to them unless I connect to a Cisco switch on our existing network. I can not ping or telnet to them from a normal PC.

Any ideas?

Many thanks.

Mike.

Hi,

if the 6500 is used as a "dumb edge switch" you might need a L3 device doing the routing between PC VLAN and 6500 management VLAN, i.e. where the IP address resides. Also make sure the new 6500 does have a proper default gateway assigned. Last not least make sure the IP address/mask settings are correct. But I am assuming this is ok, as you would not be able to telnet into the box from another switch.

The two orignal CAT's have routers in them, E.G. the layer 3 routing is done by these.

All ip addresses and gateways are in place and set up correctly.

This is just a strange one, perhaps the config of the ether channel is incorrect or something

There are no access lists configured.

"Can u verify weather the management vlan is allowed on this ether-channel"

I do not know if the managment Vlan is allowed on this ether channel!! What would the command be to allow it? Do i need to wright a command to allow it? Does it just not pass the managment VLAN by default?

Many thanks.
