Switch 6108 and Series 4100gl Switches

You can designate a port for monitoring inbound (ingress) traffic of other ports and of static trunks on the switch. The switch monitors the network activity by copying all traffic inbound on the specified interfaces to the designated monitoring port, to which a network analyzer can be attached.

 

Series 2600, 2600-PWR, and 2800 Switches

 

You can designate a port for monitoring inbound (ingress) and outbound

 

(egress) traffic of other ports and of static trunks on the switch. The switch

 

monitors the network activity by copying all inbound and outbound traffic on

 

the specified interfaces to the designated monitoring port, to which a network

 

analyzer can be attached.

 

The instructions below apply to all of the switches covered in this manual.

 

When using a Series 2600, 2600-PWR, and 2800 Switch, both inbound and

 

outbound traffic is sent to the monitoring port.

 

 

N o t e

Port trunks cannot be used as a monitoring port.

 

It is possible, when monitoring multiple interfaces in networks with high

 

traffic levels, to copy more traffic to a monitor port than the link can support.

 

In this case, some packets may not be copied to the monitor port.
