Layer 2 Switching | 31 |
DESTROY SWITCH TRUNK=trunk
Port trunk groups can only be destroyed on the switch if no ports belong to them.
All the ports in a trunk group must belong to the same VLAN. Ports in a trunk group can be added to other VLANs, either as individual ports or as an entire group. A port in a trunk group cannot be deleted from any of the VLAN(s) to which the whole trunk group belongs, unless it is first removed from the trunk group. The members of a trunk group can be specified when it is created, and ports can be added to or removed from a trunk group using the commands:
ADD SWITCH TRUNK=trunk
DELETE SWITCH TRUNK=trunk
Ports which are members of a trunk group must operate in full duplex mode. When a port is added to a trunk group, the speed setting for the group overrides the speed setting previously configured for the port. When a port is removed from a trunk group, the port returns to its previously configured speed and duplex mode settings. The speed of the trunk group can either be specified when it is created, or set using the command:
SET SWITCH TRUNK=trunk
[SELECT={MACSRCMACDESTMACBOTHIPSRCIPDESTIPBOTH}]
[SPEED={10M100M1000M}]
The SELECT parameter specifies the port selection criterion for the trunk group. Each packet to be sent on the trunk group is checked, using the selection criterion, and a port in the trunk group chosen down which to send the packet. If MACSRC is specified, the source MAC address is used. If MACDEST is specified, the destination MAC address is used. If MACBOTH is specified, both source and destination MAC addresses are used. If IPSRC is specified, the source IP address is used. If IPDEST is specified, the destination IP address is used. If IPBOTH is specified, both the source and destination IP addresses are used. The user of the switch should choose the value of this parameter to try to spread out the load as evenly as possible on the trunk group. The default for this parameter is MACDEST.
The SPEED parameter specifies the speed of the ports in the trunk group. For gigabit ports, only the value 1000M is allowed. For switch ports, values of 10M and 100M are allowed. The default is 100M. When a port is added to a trunk group, its current speed and duplex mode settings are ignored and the port uses the speed of the trunk group and full duplex mode.
To display information about trunks on the switch, use the command:
SHOW SWITCH TRUNK[=trunk]
To display the VLANs to which the ports in the trunk groups belong, use the command:
SHOW VLAN[=ALL]
Port trunking must be configured on both ends of the link, or network loops may result.
