Enabling and disabling ISL trunking
You can enable or disable HP ISL Trunking for a single port or for an entire switch.When you execute the
portCfgTrunkPort
or
switchCfgTrunk
command to update the trunking configuration, the ports for
which the configuration applies are disabled and reenabled with the new trunk configuration. As a result,
traffic through those ports could be disrupted.
Enabling or disabling ISL trunking on one port
1. Connect to the switch and log in as admin.
2. Issue the
portCfgTrunkPort
command.
The format is:
portcfgtrunkport [slotnumber/]portnumber mode
The following example enables trunking on slot 1, port 3:
Enabling or disabling ISL trunking for all of the ports on a switch
1. Connect to the switch and log in as admin.
2. Issue the
switchCfgTrunk
command. The format is:
switchcfgtrunk mode
Mode 1 enables and mode 0 disables ISL Trunking for all ports on the switch.
The following example enables trunking all ports in the switch.
Setting port speeds
For LD ports, if a port is set to auto-negotiate port speed, the maximum speed (which is 4 Gbit/sec) is
assumed for reserving buffers for the port. This wastes buffers if the port is actually running at 2 Gbit/sec.
For LD ports, it is best to set the port speed (this applies to the SAN Switch 4/32 and 4/256 SAN
Director only).
You can set the port speed for one port or for an entire switch. Trunked ports must be set to the
same speed.
where:
slotnumber
Specifies the number of the slot in which the port blade containing the port
is located (this operand is required only for switches with slots such as the
Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director).
portnumber
Specifies the number of the port on which you want to enable or disable
trunking.
mode
Enables (1) or disables (0) trunking on the specified port.
