tcpdump-x interfaces
Configures a comma-separated list of interfaces to capture in the background.
Syntax
[no] tcpdump-x interfaces <interface-name> {continuous | duration <seconds>} [schedule-time <hh:mm:ss> [schedule-date <yyyy/mm/dd>]] [rotate-count <# files>] [snaplength <snaplength>] [sip <src-address>] | [dip <dst-address>] [sport <src-port>] [dport <dst-port>] [dot1q {tagged | untagged | both}] [ip6] [custom <custom-param>] [file-size <megabytes>]
Parameters
<interface-name> | Comma-separated list of interfaces: primary, aux, lan0_0, wan0_0 |
continuous | Start a continuous capture. |
duration <seconds> | Specifies the run time for the capture in 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 <#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 the 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. Do not use the sip, dip, sport, dport and custom parameters together when using the dot1q both option. Use the tcpdump command 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. |
file-size <megabytes> | Specifies the file size of the capture in megabytes. |
Example
amnesiac (config) # tcpdump-x interfaces inpath0_0 continuous
amnesiac (config) # tcpdump-x interfaces aux ip6 sip 2003::5

Remote management port commands
This section describes the commands for configuring the remote management port.
This remote management port is unique in that it is connected to the Baseboard Management Controller (BMC). The BMC is a central component of the Intelligent Platform Management Interface (IPMI) capabilities of the machine, which are important for reading the onboard sensors, reading and writing Electrically Erasable Programmable Read-Only Memory (EEPROMs), fan control, LED control, and in-path hardware bypass control for these models. The BMC and remote management port operate independently of the CPUs and network interfaces, which allow them to continue to operate even when the machine has hit a kernel panic, become wedged, or has been given the reload halt command.
The following appliances support remote management: CX570, CX580, CX770, CX780, CX3070, CX3080, CX5070, CX7070, CX5080, CX7080, GX10000, and IC9600. Remote port management is not supported on other platforms.
The port to access remote management capabilities varies by model.
• GX10000 models use the dedicated REMOTE port on the back of the appliance.
• CX5070, CX7070, CX5080, CX7080, and IC9600 models use the dedicated BMC port.
• CX570, CX580, CX770, CX780, CX3070, and CX 3080 models do not have a separate remote port but share it with the Primary and Aux ports.
See the installation guide for your appliance to see the exact location of the port.
For details on configuring the remote management port, see
remote ip address.
Access to the SteelHead through the remote management port requires the use of the IPMI tool utility. You can download a Linux version at http://sourceforge.net/projects/ipmitool/files/.
