Defect ID: DEFECT000301286
Technical Severity: High
Summary: Routes are not properly redistributed after trunk group loses a trunk member.
Symptom: In a setup with 8G switches running exchanged base route policy, the routes are not
rebalanced properly after a trunk group loses a member. This may cause performance to
be sluggish on 8G switches fabric if there happens to be a slow drain device using the
lower bandwidth links to further congest the fabric. This only impacts 8G switches.
Workaround: Keep trunk groups with equal bandwidth.
Feature: Field Escalation
Function: FC Layer 2 Routing
Probability: Medium
Found in Release: FOS6.2.1
Service Request ID: 433171
Where Else Fixed: FOS6.3.2
