Shows the remote end advertised ability.

Syntax Description

ports Specifies ports.
port_list Lists the ports that you want remote end advertised ability information on.
advertised Selects showing auto-negotiation advertised capabilities.



Usage Guidelines

Auto-negotiation is an Ethernet feature that facilitates the selection of port speed, duplex, and flow control between the two members of a link. It first shares these capabilities, and then selects the fastest transmission mode that both ends of the link can support.

This command shows the remote end of the link‘s advertised ability, up to 1Gbps speed only, for duplex and flow control. This command is not supported on Extended Edge Switching bridge port extenders (BPE) ports.


The following example shows the advertised ability for the remote end for ports 1 and 9:

# show port 1 9 advertised
                   10BaseT     100BaseT    100X        1000BaseT   1000X       Pause
