Configuring The Drb Priority Of A Trill Port; Configuring The Link Cost For A Trill Port - HP 5920 Series Configuration Manual

Step
1. Enter system view.
2. Enter Layer 2 Ethernet
or aggregate
interface view.
3. Configure the link
type of the TRILL port.

Configuring the DRB priority of a TRILL port

On a broadcast network, TRILL must elect a DRB. An RB with a higher DRB priority is preferred in DRB
election. When two RBs have the same DRB priority, the RB with a higher MAC address takes
precedence.
To configure the DRB priority of a TRILL port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet or
aggregate interface
view.
3. Configure the DRB
priority of the TRILL port.

Configuring the link cost for a TRILL port

The link cost of a TRILL port can be automatically calculated by the system or manually configured.
A manually configured link cost takes precedence over a calculated link cost.
•
If no configured link cost exists and automatic link cost calculation is enabled, the calculated link
•
cost takes effect.
• If no configured link cost exists and automatic link cost calculation is disabled, the default link cost
of 2000 is used.
The system automatically calculates the link cost of a TRILL port by using the following formula: link cost
= 20000000000000/interface baud rate.
To configure the link cost for a TRILL port:
Step
1. Enter system view.
2. Enter TRILL view.
3. Enable automatic link cost
calculation for TRILL ports.
4. Return to system view.
