Hi Venkatesh,
Do you mean 802.1D With STP? It will work just fine, the only thing you have
to take care of is the native VLAN behaviour of both devices.
Foundry tags all VLANS, cisco switch can be configured to tag (vlan dot1q
tag native) native vlan or not. So the native VLAN on the cisco doesn't make
it throughout the foundry network. You can either tag the native vlan on the
cisco, OR.....
You can enable dual-mode port config on the foundry's interface to the
cisco, see example below
Vlan 10
Tag eth 1
!
Vlan 11
Tag eth 1
!
Int e 1
Dual-mode 10
With this configuration you tell the foundry to accept tagged and untagged
ports on ethernet 1.
One option regarding STP you have to look out for is the command "pvst-mode"
under the interface:
http://www.foundrynet.com/services/documentation/srcli/Interface_cmds.html#w
p126004
Per default the foundry reverts to cisco PVST BPDU when it receives one. If
you already know that PVST will be "offered" to the foundry just hard-code
it in, you never know!

Henk

Onderwerp: OT: SPT between CISCO and FOUNDRY
Hi Guys,
I wonder if you guys have come across any starnge behavior/issues when
running SPT between Cisco and Foundry devices. I am about to deploy few
cisco 6500 switches into a pure foundry network that runs STP and so trying
to get prepared for any unexpected surprises :-).
Thank you,
Venkatesh
