Thanks. > Not exactly CRS-3, but in one deployment of ASR9k with Eth-Bundles we've used both WANPHY and OTU2e in order to speed up link error detection. From what we've gathered for single (non-bundle) links WANPHY and OTN2e is always faster and what's more important can start the switchover when errors reach certain level, not after the link failed completely. kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
