4.3.3.BASE

Description (partial)

Symptom:

A router with active and standby RP is running IOS-XR 4.2.4. On the standby
RP, an ACL is configured and applied to the management interface. An ISSU
is then performed, to upgrade the system from 4.2.4 to 4.3.3. After the
upgrade, the originally standby RP goes active. It is then discovered
that the management interface ACL configuration is missing.


Conditions:

- An ACL must have been applied onto the management interface on standby RP
- The ISSU upgrade involves specific IOS-XR releases. The problem is introduced
  in IOS-XR 4.3.1. If the pre-upgrade release is prior to 4.3.1, and the post-upgrade
  release is after 4.3.1 (inclusive), this problem may occur.
