Web Agent Procedure

Web Agent Procedure

To use the Web Agent to set up port mirroring on a switch in Fabric mode 2:

Expand the Modules & Ports folder.
Click Port Mirroring.

The Port Mirroring Information page opens (Figure 23-6). Table 23-5 provides an explanation of each field on the Web page.

Figure 23-6. Port Mirroring Information Web Page

See Table 23-4, for the specific port ranges that you can mirror on each type of module.

Table 23-4. Port Ranges for Fabric Mode 2 Port Mirroring
Module	Port ranges that you can mirror
4-port gigabit modules	1–2 3–4 Any single port You can mirror any four single ports simultaneously (one port per channel). However you cannot mirror a port range and a single port within that range simultaneously. Example: You can mirror port 1 on channel 1, port 2 on channel 2, and port 3 on channel 3 simultaneously. However, you cannot mirror ports 1 through 2 on channel 1 and port 2 on channel 2 simultaneously.
8-port gigabit modules	1–4 5–8 Any single port You can mirror any four single ports simultaneously (one port per channel). However you cannot mirror a port range and a single port within that range simultaneously. Example: You can mirror port 1 on channel 1, port 2 on channel 2, and port 3 on channel 3 simultaneously. However, you cannot mirror ports 1 through 4 on channel 1 and port 2 on channel 2 simultaneously.
24-port 10/100 modules	1–12 -- any 1 port or the entire range. 13–24 -- any 1 port or the entire range. If you mirror a single port, you can mirror only 1 port per range at a time. Example: You can mirror port 1 on channel 1 and port 13 on channel 2 simultaneously. However, you cannot mirror port 1 on channel 1 and port 2 on channel 2 simultaneously.
48-port 10/100 modules	1–12 -- any 1 port or the entire range. 13–24 -- any 1 port or the entire range. 25–36 -- any 1 port or the entire range. 37–48 -- any 1 port or the entire range. If you mirror a single port, you can mirror only 1 port per range at a time. Example: You can mirror port 1 on channel 1 and port 13 on channel 2 simultaneously. However, you cannot mirror port 1 on channel 1 and port 2 on channel 2 simultaneously.

Select the Channel and the associated port from the Source Port column pull-down menu.
In the Mirror Port column pull-down menu, select the port to which you want to mirror traffic.

Both the source port and mirror port must either:

Be on the same VLAN and have the same VLAN binding

Have VLAN binding set to bind to all

NOTE: The source port and the mirror port must be different physical ports.

In the Direction/Filter column, select the direction of traffic that you want to mirror and the filter that you want to set up, if any.

You can set up a MAC address filter to monitor only traffic with a specific source MAC address or destination MAC address.

NOTE: Do not set the source MAC address in the Destination/Filter field.Setting a Source MAC address in the Destination MAC filter causes traffic to be improperly monitored.

In the Sampler Type column, select how often you want the mirror port to receive traffic samples.

Do one of the following:


IF you select...	THEN...
Periodic in the Sampler Type column	In the Max Packets per Second column, enter the maximum number of packets per second that you want the mirror port to receive.
Disable or Always in the Sampler Type column	Go to step 8.

If you selected Transmit/DA Filter in the Direction/Filter field, enter the MAC address that you want to monitor in the DA Filter field for the port mirror.
If you selected Receive/SA Filter in the Direction/Filter field, enter the MAC address that you want to monitor in the SA Filter field for the port mirror.

Click Apply.

Table 23-5. Port Mirroring Information Web Page Parameters
Parameter	Definition
Channel	Displays the channel number. Four channels are provided for monitoring traffic, so you can monitor four different ports or port ranges simultaneously.
Source Port	The port that you want to mirror.
Mirror Port	The port to which you want to mirror traffic. Both the source port and mirror port must either: Be on the same VLAN and have the same VLAN binding or Have VLAN binding set to bind to all
Direction/Filter	The direction of traffic that you want to mirror and the filter that you want to set up, if any. Options are: Receive/None-Mirrors all receive traffic. Transmit/None-Mirrors all transmit traffic. Both/None-Mirrors all transmit and receive traffic. Receive/SA Filter-Mirrors receive traffic that has the source MAC address that you specify in the Source MAC (SA) field. Transmit/DA Filter-Mirrors transmit traffic that has the destination MAC address that you specify in the Destination MAC (DA) field.
Sampler Type	Specifies how often you want the mirror port to receive traffic samples. Options are: Disable Always Periodic
Max Packets per Second	The maximum number of packets per second that you want the mirror port to receive. Enter a number in this field only if you selected Periodic in the Sampler Type field.
Channel Filter	Displays the channel number.
Source MAC (SA)	The source MAC address that you want to mirror traffic for. Enter a MAC address in this field only if you selected Receive/SA Filter in the Direction/Filter field.
Destination MAC (DA)	The destination MAC address that you want to mirror traffic for. Enter a MAC address in this field only if you selected Transmit/DA Filter in the Direction/Filter field.
