Specifies the speed of a FastEthernet (10/100) or GigabitEthernet (10/100/1000) port. This is the speed at which the port can receive and transmit the data.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000


speed [10|100|1000|auto]


speed [10|100|1000|auto]
10 Forces 10 Mbps operation
100 Forces 100 Mbps operation
1000 Forces 1000 Mbps operation
auto Port automatically detects its operational speed based on the port at the other end of the link. Select this option to enable the port to automatically exchange information about data transmission speed and duplex capabilities. Auto negotiation is helpful when in an environment where different devices are connected and disconnected on a regular basis.

Usage Guidelines

Set the interface speed to auto detect and use the fastest speed available. Speed detection is based on connected network hardware.
