Configuring Port Parameters
Changes to port parameters are made using the interface <port> command to
adjust to attached devices or other network requirements. Follow the
procedures in this section to set the following port parameters:
■
Activating or disabling ports
Modifying port speed
■
■
Modifying port mode
■
Disabling or re-enabling flow control
Assigning a description to an interface
■
■
Setting maximum rate limits (2-port 10-Gig Module only)
To modify Layer 2, Layer 3, or Layer 4 features on a port, see the appropriate
section in other chapters. For example, to modify Spanning Tree Protocol
(STP) parameters for a port, see
Specifying Slot and Port Numbers
The term port refers to a physical connector on an interface module installed
in the switch. At the CLI, each port is referred to in the following manner:
<type> <slot-number>/<port-number>
where:
<type> is the type of module and/or the type of logical or physical
interface, and is one of the following:
ethernet – Ethernet (IEEE 802.3[z])
–
gigabitethernet – GigabitEthernet (IEEE 802.3z)
–
lag – Link aggregation interface
–
loopback – Loopback interface
–
management – Management interface
–
null – Null interlace
–
tengigabitethernet – 10 GigabitEthernet (IEEE 802.3ae)
–
vlan – VLAN interface
–
<slot-number> is determined by the switch model and the physical slot
in which the module is installed (see
<port-number> is the number assigned to the physical connector on the
interface module. The range and assignment of port numbers varies by
the type of module. Ports are numbered 1 to n, top to bottom.
