Alarm Messages Chapter 4 Troubleshooting Table 4-4 IEEE 802.17 RPR Steer Messages (continued) Alarm RPR-IEEE1/1 protected on span EAST (span WEST Long Request Signal Fail) RPR-IEEE1/1 protected on span EAST (span WEST Long Request Signal Degrade) Description Neighbor node protected due to signal fail Neighbor node protected due to signal degrade Solution Investigate signal fail on neighbor node. Investigate why the short path request was not received. Check other problems on the short span as indicated on the neighbor node. Investigate signal degrade on neighbor node. Investigate why short path request was not received. Check other problems on the short span as indicated on the neighbor node. Table 4-5 IEEE 802.17 RPR Un-Steer Messages Alarm RPR-IEEE1/1 unprotected on span EAST (protection cause cleared) Description Protection cleared; Wait to Restore timer expired. Table 4-6 Other IEEE 802.17 RPR Alarm Messages Alarm RPR-IEEE1/1 Ringlet1 reserved A0 bandwidth has exceeded line rate RPR-IEEE1/1 Ringtlet0 reserved A0 bandwidth has exceeded line rate RPR-IEEE1/1 MAX Stations Exceeded RPR-IEEE1/1 Effective jumbo pref on ring is set for jumbo frames Description Solution The amount of total A0 bandwidth on Ringlet1 reserved by all nodes on the ring exceeds the line rate Check current A0 allocations on each station using the show rpr-ieee rate-limit command. Change the A0 allocation on the ring by using the rpr-ieee tx-traffic reserved CLI command. The amount of total A0 bandwidth on Ringlet0 reserved by all nodes on the ring exceeds the line rate Check current A0 allocation on each station using the show rpr-ieee rate-limit command. Change the A0 allocation on the ring by using the rpr-ieee tx-traffic reserved CLI command. Too many stations have been discovered in the topology (maximum number of ring stations is 255) Execute the show rpr-ieee topology commandto verify stations. Reduce the numer of stations in the ring. All stations on the ring now support jumbo frame preference, MTU for the ring has been changed to JUMBO MTU (9100 bytes). None. Remove jumbo preference on stations to revert to REGULAR MTU (1500 bytes) 4-16 Cisco 10720 Internet Router Installation and Configuration Guide 78-13062-10
