15.1(2)SG4 15.4(2.16)S

Description (partial)

Symptom:
A Catalyst 4500 Supervisor 7-E, 7L-E or 8-E may experience an unexpected crash of the 'iosd' process. On a dual-supervisor system this should result in a switchover.

Conditions:
This is seen when ACLs are applied to a switchport. Note that these ACLs do not need to be manually applied: many features (such as 802.1x, IP Source Guard, etc) will apply dynamic ACLs which are not visible to the user.
