REF: BRIDGE CRITERIA AND MANUAL ENTRY OF PORT PRIORITY MULTIPLES OF 16
Posted on 2011-02-27
RERERING TO ELECTION CRITERIA BUT SPECIFIC TO 'LOWEST SENDER PORT ID'
If there is a design of switches in the form of a tree or whatever, for example and the 'Root Bridge/Switch' is at the TOP and a company wished to add a 'Manual entry' ie to prioritize each of their department switches.
I have read it can be done as although the default priority is 128, this can be changed specifically for individual vlans in multiples of 16 ie:
Lowest Sender Port ID
- consists of Port priority
- And port ID (port number)
- Port priority can be configured
- config-if)#spanning-tree vlan 10 port-priority 16, or 32 or 48 etc etc
If this is true does that mean if a company does NOT have the relevant IOS features to use 'SAY' 'RSTP+ OR MST', which have the feature, 1 instance per vlan, is the above an 'OLD' feature which was replace by 'RSTP+ OR MST' for example?
