Switch Port-Mirroring
Summit 300-48 Switch Software User Guide 59
• Ports on the switch are divided into a maximum of five groups.
• Port-based and round-robin load sharing algorithms do not apply.
• A redundant load share group can only include ports from the following ranges: 1:1-1:24, 1:25-1:48,
1:49-1:52.
To define a load-sharing group, you assign a group of ports to a single, logical port number. To enable
or disable a load-sharing group, use the following commands:
enable sharing <port> grouping <portlist> {address-based}
disable sharing <port>
NOTE
A maximum of eight ports in a load-share group is allowed.
Load-Sharing Example
This section provides an example of how to define load-sharing on a Summit 300-48 switch.
Load-Sharing on a Summit 300-48 Switch
The following example defines a load-sharing group that contains ports 1:9 through 1:12, and uses the
first port in the group as the master logical port 9:
enable sharing 1:9 grouping 1:9-1:12
In this example, logical port 9 represents physical ports 1:9 through 1:12.
When using load sharing, you should always reference the master logical port of the load-sharing group
(port 1:9 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 configuration 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 is defined by the following criteria:
• Physical port — All data that traverses the port, regardless of VLAN configuration, is copied to the
monitor port.
