i. Add a new IP address/network filter:
(config network analyzer name)> add filter address end
(config network analyzer name filter address 0)>
ii. Set the IPv4 or IPv6 address (and optional netmask):
(config network analyzer name filter address 0)> address ip_
address[/netmask]
(config network analyzer name filter address 0)>
iii. Set whether the filter should apply to packets when the IP address/network is the
source, the destination, or both:
(config network analyzer name filter address 0)> match value
(config network analyzer name filter address 0)>
where value is one of:
iv. (Optional) Set the filter should ignore packets from this IP address/network:
(config network analyzer name filter address 0)> ignore true
(config network analyzer name filter address 0)>
By default, is option is set to false, which means that the filter will capture packets
from this IP address/network.
v. Repeat these steps to add additional IP address filters.
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.
