When autonegotiation isdisabled, the hardware is configured for a single (fixed) speed and duplexvalue. When auto-negotiation is enabled, the advertisement made bythe switch is a constant value based upon all speed and duplex modessupported by the hardware. When auto-negotiating, the switch selects thehighest common operating mode supported between it and its link partner.This section covers:• "show auto-negotiation-advertisements command" (page 245)• "show auto-negotiation-capabilities command" (page 245)Nortel Ethernet Routing Switch 2500 SeriesOverview — System ConfigurationNN47215-500 (323162-B) 02.02 Standard4.1 19 November 2007Copyright © 2007, Nortel Networks.
