b. To create a filter that either captures or ignores packets that use a particular IP protocol:
i. Add a new IP protocol filter:
(config network analyzer name )> add filter protocol end
(config network analyzer name filter protocol 0)>
ii. Use the ? to determine available protocols and the appropriate format:
(config network analyzer name filter protocol 0)> protocol ?
IP protocol to capture or ignore: IP protocol to capture or
ignore.
Format:
ah
esp
gre
icmp
icmpv6
igmp
ospf
other
tcp
udp
vrrp
Current value:
(config network analyzer name filter protocol 0)>
iii. Set the protocol:
(config network analyzer name filter protocol 0)> protocol value
(config network analyzer name filter protocol 0)>
iv. If other is set for the protocol, set the number of the protocol:
(config network analyzer name filter protocol 0)> protocol_other
value
(config network analyzer name filter protocol 0)>
where value is an integer between 1 and 255 and represents the the number of the
protocol.
v. (Optional) Set the filter should ignore packets from this protocol:
(config network analyzer name filter protocol 0)> ignore true
(config network analyzer name filter protocol 0)>
By default, is option is set to false , which means that the filter will capture packets
from this protocol.
vi. Repeat these steps to add additional protocol filters.
