Chapter 4 Troubleshooting Alarm Messages Table 4-2 IEEE 802.17 RPR Wrap Messages Alarm Description Solution RPR-IEEE1/1 wrapped on span East (span WEST User Request Forced Switch) User initiated forced switch on User initiated, none. span WEST on node RPR-IEEE1/1 wrapped on span EAST (span WEST User Request Manual Switch) User initiated manual switch on span WEST on node User initiated, none. RPR-IEEE1/1 wrapped on SONET Layer 1 signal fail span EAST (span WEST detected Self Detect Signal Fail) Investigate Keepalive failure. Wrap occurred. Keepalive failure-SLOS, SLOF, LSF, or LAIS. RPR-IEEE1/1 wrapped on span EAST (span WEST Span Neighbor Signal Degrade) SONET Layer 1 signal fail detected Investigate Keepalive failure. Wrap occurred. Keepalive failure-LSD. RPR-IEEE1/1 wrapped on span EAST (span WEST Self Detect Wait to Restore [WTR]) Wrap cleared, node initiated; Wait to Restore (WTR) state WTR period is 10 to 360 seconds (user configured), node will unwrap at end of WTR. None. RPR-IEEE1/1 wrapped on span EAST (span WEST Span Neighbor Forced Switch) Neighbor node Forced Switch User initiated, none. initiated by user. Node wrap to protect failed span RPR-IEEE1/1 wrapped on span EAST (span WEST Span Neighbor Manual Switch) Neighbor node Manual Switch User initiated, none. initiated by user. Node wrap RPR-IEEE1/1 wrapped on Neighbor node wrapped due to Investigate the signal degrade on span EAST (span WEST signal fail neighbor node. Span Neighbor Signal Fail) RPR-IEEE1/1 wrapped on span EAST (span WEST Span Neighbor Signal Degrade) Neighbor node wrapped due to Investigate the signal degrade on signal degrade neighbor node. RPR-IEEE1/1 wrapped on span EAST (span WEST Span Neighbor WTR) Wrap cleared, node initiated; Wait to Restore state WTR period is 0 to 1440, or never (user configured), node will unwrap at end of WTR. None. Setting WTR to never will prevent the node from unwrapping. RPR-IEEE1/1 wrapped on span EAST (span WEST Long Request Forced Switch) Neighbor node Forced Switch initiated by user; Node wrap to protect failed span; Secondary problem on the short path Investigate why the short path request was not received. Check other problems on the short span as indicated on the neighbor node. 78-13062-10 Cisco 10720 Internet Router Installation and Configuration Guide 4-13
