capture-name <capture-name> | Specifies a capture name to help you identify the TCP Dump. The default filename uses the following format: <hostname>_<interface>_<timestamp>.cap Where hostname is the hostname of the SteelHead, interface is the name of the interface selected for the trace (for example, lan0_0, wan0_0), and timestamp is in the yyyy-mm-dd-hh-mm-ss format. Note: The cap file extension is not included with the filename when it appears in the capture queue. |
continuous | Starts a continuous capture. |
buffer-size <buffer-size> | Specifies the size in KB for all packets. |
duration <seconds> | Specifies the run time for the capture in seconds. The default is 30 seconds. |
schedule-time <hh:mm:ss> | Specifies a time to initiate the trace dump in the following format: hh:mm:ss. |
schedule-date <yyyy/mm/dd> | Specifies a date to initiate the trace dump in the following format: YYYY/MM/DD |
rotate-count <no-of-files> | Specifies the number of files to rotate. |
snaplength <snaplength> | Specifies the snap length value for the trace dump. The default value is 1518. Specify 0 for a full packet capture (recommended for CIFS, MAPI, and SSL traces). |
sip <src-address> | Specifies a comma-separated list of source IP addresses. The default setting is all IP addresses. |
dip <dst-address> | Specifies a comma-separated list of destination IP addresses. The default setting is all IP addresses. |
sport <src-port> | Specifies a comma-separated list of source ports. The default setting is all ports. |
dport <dst-port> | Specifies a comma-separated list of destination ports. The default setting is all ports. |
dot1q | Specifies one of the following to filter dot1q packets: • tagged - Capture only tagged traffic. • untagged - Capture only untagged traffic. • both - Capture all traffic. Note: Do not use the sip, dip, sport, dport and custom parameters together when using the dot1q both option. Use the tcpdump command instead to capture this information. For detailed information about dot1q VLAN tunneling, see your networking equipment documentation. |
ip6 | Specifies IPv6 packets for packet capture. |
custom <custom-param> | Specifies custom parameters (flags) for packet capture. You need to enclose the customer parameter in quotes if it contains more than one word. |
file-size <megabytes> | Specifies the file size of the capture in megabytes. |
