Nortel Networks NN46110-602 manual Configuring a capture object

116 Chapter 5 Packet capture

For example, enter the following command:

CES# capture add test1 ?

atm	ATM interface capture
bri	Bri interface	capture
dial	Dial interface capture
FastEthernet	Fast Ethernet	interface capture
GigabitEthernet	Gigabit Ethernet interface capture
global	Global RAW IP	capture
serial	Serial interface capture
tunnel	Tunnel capture

2Create a capture object by specifying an object name and type.

In the following example, you create a capture object called test_ethernet1 that captures traffic on Ethernet interface 1/2.

CES# capture add test_ethernet1 FastEthernet 1/2

CES#

In the following example, you create a capture object called test_tunnel that captures tunnel traffic.

CES# capture add test_tunnel tunnel

CES#

Configuring a capture object

After you create a capture object, you can configure it to capture a subset of the traffic that travels over the physical interface, tunnel, or the VPN Router as a whole. You can configure a capture object to do the following:

•capture inbound or outbound traffic or both

•capture a non-default number of octets from each packet

•apply an interface filter to the object

•configure start and stop triggers for the object

•specify whether the capture stops when the buffer is full or whether new data overwrites the existing data
