i. Add a new IPaddress/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 IPaddress/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:
n
source: The filter will apply to packets when the IPaddress/network is the
source.
n
destination: Thefilter will apply to packets when the IPaddress/network is
the destination.
n
either: The filter will apply to packets when the IPaddress/network is either
the source or the destination.
iv. (Optional) Set the filter should ignore packets from this IPaddress/network:
(config network analyzer name filter address 0)> ignore true
(config network analyzer name filter address 0)>
By default, isoption is set to false, which meansthat the filter will capture packets
from this IPaddress/network.
v. Repeat these steps to add additional IPaddress filters.
b. To create a filter that either captures or ignores packetsthat use a particular IPprotocol:
i. Add a new IPprotocol 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.
