CSCvj74332 | Not able to deploy ISR-WAAS in ISR-4321 router installed with IOS-XE-16.9.x version |
The CPU share for the container services has been reduced in Cisco IOS® XE Software Release 16.9.x, which leads to Integrated Services Router-Wide Area Application Services (ISR-WAAS) installation failure. This issue is specific to the ISR-WAAS 200 model that runs on ISR 4321 when used with Cisco IOS XE Software Release 16.9.1.
Due to the resource allocation changes for container services in ISR 4321, these versions are impacted for ISR-WAAS 200:
WAAS Version 6.x (all versions earlier than 6.4.1b) will fail to deploy on an ISR 4321 router with Cisco IOS XE Software Release 16.9.x or later; and WAAS version 6.x (all versions earlier than 6.4.1b) will not come up if Cisco IOS XE is upgraded from an earlier release to 16.9.x or later.
Customers who run Cisco IOS XE Software Release 16.9.x or later with an affected WAAS release should upgrade their WAAS software to 6.4.1b (or later) as shown in this table:
Router | Cisco IOS Version | WAAS Version | Impacted |
---|---|---|---|
ISR 4321 | 16.8.x or earlier | All supported versions | No |
16.9.x or later | 6.x (All versions earlier than 6.4.1b) | Yes | |
5.x, 6.4.1b or later | No |
Note: Once WAAS is deployed with version 6.4.1b (or later), you can downgrade the WAAS version to any of the supported versions (including impacted versions) via the WAAS User Interface.
