debug interface ge?
debug interface ge?
To enable packet tracing on a Gigabit Ethernet interface, use the debug interface ge? command. To
disable packet tracing, use the no form of this command.
debug interface ge? trace [pktcnt nn] [pktsize nn] enable
no debug interface ge? trace enable
Syntax Description
Defaults IP packet tracing for all Gigabit Ethernet interfaces is disabled by default. The maximum trace size is
128, and all packets use a circular trace buffer.
Command Modes Administrator.
Command History
Usage Guidelines The debug interface ge? command is designed for debug purposes, and should be used under the
guidance of a Cisco Technical Support professional.
• Use the pktcnt keyword to specify the maximum number of packets to be traced. IP packet tracing
will automatically be disabled when the specified number of packets is traced, or the trace buffer
fills up. If a packet count is not specified, a circular trace buffer is used. The default trace buffer size
is 131072 bytes.
• Use the pktsize keyword to specify the maximum number of bytes to trace per packet. This value
must be in the range of 14 to 1024. The default number of bytes to trace per packet is 128.
• Use the show debug interface command to display statistics about the packet trace and to display
the contents of the trace buffer in hex.
Note IP packet tracing must be disabled on the interface before the trace buffer can be displayed.
ge? Enable IP trace for the specified Gigabit Ethernet interface. When you type
the debug interface ge? command, the CLI lists the interfaces available.
You cannot specify a nonexistent interface.
trace Keyword indicating IP packet tracing will be enabled.
pktcnt nn (Optional) Specify the maximum number of packets to be traced. nn must
be a value greater then zero (0). If not specified, a circular trace buffer is
used. This is the default.
pktsize nn (Optional) Specify the maximum number of bytes to trace per packet. Valid
values are 14 to 1024, inclusive. The default is 128.
