Capture to and from IP host 10.0.0.1 but filter out ports 22 and 80:
digi.router> analyzer filter ip host 10.0.0.1 and not (port 22 or port
80)
Example Ethernet capture filters
Capture Ethernet packets to and from host 00:40:FF:0F:45:94:
digi.router> analyzer filter ether host 00:40:FF:0F:45:94
Capture Ethernet packets from host 00:40:FF:0F:45:94:
digi.router> analyzer filter ether src 00:40:FF:0F:45:94:
Capture Ethernet packets to host 00:40:FF:0F:45:94:
digi.router> analyzer filter ether dst 00:40:FF:0F:45:94
Show captured data traffic
To view the captured data traffic, use the show analyzer command. The command output shows the
following information for each packet:
n The packet number
n The timestamp for when the packet was captured
n The length of the packet and the amount of data captured
n Whether the packet was sent or received by the device
n The interface on which the packet was sent or received
n A hexadecimal dump of the packet of up to 256 bytes
n Decoded information of the packet
The output uses indents received packets as a visual cue for sent and received packets.
The output is paged. Press the spacebar to view the next page of data. Enter Q to navigate to the
command prompt.
