Load-Sharing Examples
This section provides examples of how to define load-sharing on modular and stand-alone switches.
Cross-Module Load Sharing on a Modular Switch
The following example defines a load-sharing group that contains ports 9 through 12 on slot 3, ports 7
through 10 on slot 5, and uses the first port in the slot 3 group as the master logical port 9:
enable sharing 3:9 grouping 3:9-3:12, 5:7-5:10
In this example, logical port 3:9 represents physical ports 3:9 through 3:12 and 5:7 through 5:10.
When using load sharing, you should always reference the master logical port of the load-sharing group
(port 3:9 in the previous example) when configuring or viewing VLANs. VLANs configured to use
other ports in the load-sharing group will have those ports deleted from the VLAN when load sharing
becomes enabled.
Single-Module Load Sharing on a Modular Switch
Single-module load sharing is supported on all modular switches. The following example defines a
load-sharing group that contains ports 9 through 12 on slot 3 and uses the first port as the master
logical port 9:
enable sharing 3:9 grouping 3:9-3:12
In this example, logical port 3:9 represents physical ports 3:9 through 3:12.
When using load sharing, you should always reference the master logical port of the load-sharing group
(port 3:9 in the previous example) when configuring or viewing VLANs. VLANs configured to use
other ports in the load-sharing group will have those ports deleted from the VLAN when load sharing
becomes enabled.
Verifying the Load-Sharing Configuration
The screen output resulting from the
show ports sharing
command lists the ports that are involved in
load sharing and the master logical port identity.
Switch Port-Mirroring
Port-mirroring configures the switch to copy all traffic associated with one or more ports. The monitor
port can be connected to a network analyzer or RMON probe for packet analysis. The system uses a
traffic filter that copies a group of traffic to the monitor port.
The traffic filter can be defined based on one of the following criteria:
• Physical port —All data that traverses the port, regardless of VLAN configuration, is copied to the
monitor port.
