Configuring Packet Sniffing; Enabling Packet Sniffing; Limiting Packet Sniffing To Specific Interfaces - Avaya G250 Administration

Configuring packet sniffing

Packet sniffing configuration consists of the following steps:
1.

Enabling packet sniffing

2.

Limiting packet sniffing to specific interfaces

3. Creating a capture list
4. Defining rule criteria for a capture list
5. Viewing the capture list
6. Applying a capture list
7. Configuring packet sniffing settings
8. Starting the packet sniffing service
Enabling packet sniffing
Since the packet sniffing service presents a potential security breach, the administrator must
first enable the service on the G250/G350 before a user can start capturing packets. Use the
capture-service command to enable the packet sniffing service.
Note:
The packet sniffing service can only be enabled by an administrator connecting
Note:
with a serial cable to the G250/G350 console port.
To disable packet sniffing, use the no capture-service command.
Limiting packet sniffing to specific interfaces
By default, the packet sniffing service captures packets and Ethernet frames from all the
router's interfaces. You can use the capture interface command to limit packet sniffing to
a specific interface. For example, use the following command to limit packet sniffing to the Fast
Ethernet interface:
G350-001(super)# capture interface FastEthernet 10/2
Done!
G350-001(super)#
Use the following command to enable packet sniffing on all available interfaces:
G350-001(super)# capture interface any
Done!
G350-001(super)#
that specifies which packets to capture
