Parameters
pcb pcb-index: Displays detailed UDP connection information for the specified PCB. The value range for the pcb-index argument is 1 to 16.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays detailed information about UDP connections for all cards.
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays detailed information about UDP connections for all cards.
Usage guidelines
The detailed information includes socket creator, status, option, type, protocol number, source IP address and port number, and destination IP address and port number for UDP connections.
