Using the debug filter command
B
Pattern matching filter settings
You can set up a filter to capture packets that contain a pattern of a specified length, starting from
a given offset from the beginning of the packet.
Example:
Virtual ADX(debug-filter-spec-1)#pattern 24 2 1023
Syntax: pattern offset length pattern-in-hex
The offset variable is the number of bytes from the start of the packet.
The length variable is the length of the pattern in bytes. You can specify between 1 - 32 bytes.
The pattern-in-hex variable is the pattern to match. The length of the pattern must be equal to the
number of bytes specified with the length variable.
Example:
Create a filter to look for every packet from source IP 192.168.8.1 going to destination IP
192.168.8.222 - destination port 80:
Virtual ADX(debug-filter-spec-1)#ip src 192.168.8.1
Virtual ADX(debug-filter-spec-1)#ip dest 192.168.8.222
Virtual ADX(debug-filter-spec-1)#tcp dest 80
To show the currently applied settings for the filter, use the show command:
Virtual ADX(debug-filter-spec-1)#show
