Command Syntax and Usage | ||
---|---|---|
capture [-p <port range>] [-DM <Dest MAC>] [-SM <Source MAC>] [-v/vlan <vlan number>] [<bpf filter syntax>] | ||
Starts the packet capture operation and sets the packet capture option parameters (the parameters are case sensitive): ![]() You can define several ports or a range, for example capture -p 1 -p 2 -p 13-15 Note: Note: The logical relationship between ports is OR, and the logical relationship between ports to other filters is AND. ![]() ![]() Note: If you define both SM and DM, the relationship between them is AND (meaning only a match of both DM and SM is captured). The logical relationship between MACs to other filters is also AND. ![]() For an untagged port, the whole port is dedicated to this VLAN ID and all traffic of this port is captured (untagged traffic). For a tagged port, the traffic of this port is tagged and only packets with this VLAN tagging ID are captured. You can only define one VLAN ID. The logical relationship between VLAN filter to other filters is AND. If you set a VLAN filter, it is interpreted as if you provided the VLAN ID and its port. For example: — capture -v 40 (and VLAN 40 is defined on port 3) — This is interpreted as -p 3 -v 40 (and you receive packets from port 3). — capture -v 40 (and VLAN 40 is defined on port 3 and port 5) — This is interpreted as -p 3 -p 5 -v 40 (and you receive packets from port 3 or port 5). — If the port is untagged with VLAN 40 — You receive all the traffic of the port. If the port is tagged with VLAN 40, you receive all packets with VLAN tagging 40. — capture -p 16 -v 40 (and VLAN 40 is defined on port 3 and port 5) — This is interpreted as -p 16 -p 3 -p 5 -v 40 (and you receive traffic from port 3 or port 5, but with VLAN 40. You do not receive any packets from port 16, because VLAN 40 is not defined for port 16.) ![]() | ||
