20 Link Aggregation Control Protocol (LACP) Overview This chapter contains commands for Dell Force10's implementation of Link Aggregation Control Protocol (LACP) for the creation of dynamic link aggregation groups (LAGs - called port-channels in FTOS parlance). For static LAG commands, see the section Port Channel Commands in the Interfaces chapter), based on the standards specified in the IEEE 802.3 Carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications. Commands in this chapter generally are supported on all three Dell Force10 platforms - C-Series, E-Series, and S-Series - as indicated by the following symbols under command headings: c e s Commands Use the following commands for LACP: • clear lacp counters • debug lacp • lacp long-timeout • lacp port-priority • lacp system-priority • port-channel mode • port-channel-protocol lacp • show lacp In addition, an FTOS option provides hitless dynamic LACP states (no noticeable impact to dynamic LACP states after an RPM failover) on E-Series. clear lacp counters c e s Clear Port Channel counters. Syntax clear lacp port-channel-number counters Parameters port-channel-number Enter the Port Channel number to clear the counters. C-Series and S-Series Range: 1-128 E-Series Range: 1-255 for TeraScale Defaults Without a Port Channel specified, the command clears all Port Channel counters.
