Hi All,
Thanks for the inputs, actually I do find there is an option for PVST-mode (
it says PVST+ on its output)in the foundry under spanning tree configuration
and that is whay I opted for it. I am still doing my research about how I
coudl make these two boxes live happily together and also do what I want
them to do :-) OI think this shouldnt be a big job.
Device#sh <telnet@core1.eqx-nrt#sh> span
DECIMAL Number of spanning tree entries to skip before display begins
detail Show more details of STP information on each port
*pvst-mode PVST status
* vlan Show spanning tree of a VLAN
| Output modifiers
Thank you,
Venkatesh
