How many STP are possible to have on one Catalyst Switch?
Can anyone confirm if each VLan has it's own Spanning Tree priority number?
The above (second) question is in reference to Bruce Caslow's explanation in
BRS Vol. 1, Page 821, last sentence in Paragraph 2.
Any thoughts!
Thanks Regards,
You can choose to either run common (or mono) spanning tree where there is
only 1 spanning tree for all VLANs. Advantage: Less overhead.
Disadvantage: Suboptimal trees for some VLANs and a change causes one big
STP recalc. You could also choose to run PVST (Per VLAN Spanning Tree) in
which
The answer to this question depends on which Catalyst switch you are talking
about. The 2900XL's can have up to 68 VLANS and therefore you would be able
to have 64 instances of spanning tree running. Show vtp stat will show you
the possible number of vlans on your hardware.
