no form of this command.

Command History
Usage Guidelines A source port (also called a monitored port) is a switched port that you monitor for network traffic
analysis. In a single local SPAN session, you can monitor source port traffic such as received (Rx),
transmitted (Tx), or bidirectional (both).
A source port can be an Ethernet port, port channel, SAN port channel, or a VLAN port. It cannot be a
destination port.
For ERSPAN, if you do not specify both, rx, or tx, the source traffic is analyzed for both directions.
interface Specifies the interface type to use as the source SPAN port.
ethernet slot/port Specifies the IEEE 802.3z Ethernet interface to use as the source SPAN port.
The slot number is from 1 to 255 and the port number is from 1 to 128.
port-channel
channel-num
Specifies the EtherChannel interface to use as the source SPAN port. The
EtherChannel number is from 1 to 4096.
both (Optional) Specifies both ingress and egress traffic on the source port.
Note Applies to ERSPAN source port.
rx (Optional) Specifies only ingress traffic on the source port.
Note Applies to ERSPAN source port.
tx (Optional) Specifies only egress traffic on the source port.
Note Applies to ERSPAN source port.
vlan vlan-num Specifies the VLAN inteface to use as the source SPAN port. The range is
from 1 to 3967 and 4048 to 4093.
