Mirroring Configurations
Incoming or outgoing traffic from any source port can be mirrored for realtime analysis. A logic
analyzer or a RMON probe can then be attached to study the traffic crossing the source port in a
completely unobtrusive manner. When mirroring port traffic, remember the following conditions:
• The target port should be operating at the same or higher speed than the source port. If the
target port is operating at a lower speed than the source port, packets will be lost.
• For optimum performance, you should mirror three or fewer ports at any given time.
To configure a port for mirroring
1. In the left panel, click Mirroring Configurations.
2. Configure these fields.
3. Click
Apply.
4. To remove an entry, select the port and click
None.
VLAN Configurations
The switch allows the assignment of an IP interface to each VLAN. A VLAN must be configured
before setting up its IP interface. You can create either a port-based or an IEEE 802.1Q VLAN. By
default, all ports belong to an IEEE 802.1Q VLAN called “default.” Although this VLAN cannot
be deleted, all member ports can be assigned to other VLANs.
To configure GVRP globally
The global GVRP flag determines whether GVRP (Group VLAN Registration Protocol) is enabled
on the switch so that the switch can share VLAN information with other switches, and VLANs can
span multiple switches. When this flag is disabled, VLANs are confined to the physical
connections of the switch. By default, this flag is disabled.
1. In the left panel, click
VLAN Configurations.
2. In the top panel, click
Switch GVRP.
3. Use the drop-down menu to select
Enabled or Disabled.
4. Click
Apply.
Field Description
Target Port
Specifies the port where information will be duplicated and sent for capture
and network analysis. This is the port where a network analyzer would be
attached to capture packets duplicated from the source (mirrored) port.
Mirrored Port
Specifies which port to mirror and which packets to mirror. This port is the
source of the packets. Use one of the following values:
• Rx—Mirror incoming packet.
• Tx—Mirror outgoing packets.
• Both—Mirror both incoming and outgoing packets.
• None—Do not mirror.
If the port is grayed out, the port cannot be selected for mirroring.
