Table below describes the possible fields (depending on the type of port queried) and the values in the show port capabilities command output.

Table: show port capabilities Command Output Fields

Field Description

Model

Module model number

Port

Module number and port number

Type1

Port type (for example, 100BASE-FX MM, 100BASE-FX SM, or 10/100BASE-TX)

Speed1

Port speed setting (for example, auto, 100, or 1000)

Duplex

Duplex mode (half, full, auto, fdx, hdx, or no)

Trunk encap type

Trunk encapsulation type (ISL, 802.1Q, 802.10, or no)

Trunk mode

Trunk administrative status of the port (on, off, auto, desirable, nonegotiate, or no)

Channel

Status of which ports can form a channel group. The ports are shown in mod_num/port_num format. For example, 3/1-2 indicates module 3, ports 1 and 2. In addition, any ports in range [mod/1-mod/high_port] or no ports may be indicated.

Broadcast suppression

Number of packets-per-second (pps) of broadcast/multicast traffic allowed on the port (0 to 150000) or the percentage of total available bandwidth that can be used by broadcast/multicast traffic (0 to 100).

Flow control

Flow-control options that can be set (receive-[off, on, desired], send-[off, on, desired], or no)

Security

Status of whether port security is enabled (yes or no)

Membership

Method of membership assignment of a port or range of ports to a VLAN (static or dynamic)

Fast Start

Status of whether the spanning tree port fast-start feature on the port is enabled (yes or no)

QoS Scheduling

(rx-(none),tx-(none))

CoS Rewrite

Status of whether the port supports COS rewrite (yes or no)

ToS Rewrite

Status of whether the port supports TOS rewrite (IP-Precedence)

Rewrite

Status of whether the port supports inline rewrite (yes or no)

UDLD

Status of whether the port supports UDLD (Capable, Not capable)

Voice Vlan

Status of whether the port supports voice or VLAN (yes or no)

1These fields will change depending on the system configuration.


Misconceptions:

If you do not specify a mod_num, the ports on all modules are shown.

If you do not specify a /port_num, all the ports on the module are
shown.
