Jan 11, 2017
- Cisco Carrier Routing System
Known Affected Releases
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.
