Configuring an ERSPAN Type III Source Session
Purpose
Associates the ERSPAN source session number with the
VLANs (1-4096).
On Cisco Nexus 5000 Series switches, specifies the
VSAN ID number. The range is 1 to 4093. On Cisco
Nexus 5500 Series switches, you cannot configure source
VSANs.
Configures the destination IP address in the ERSPAN
session. Only one destination IP address is supported per
ERSPAN source session.
Configures the flow ID to identify the ERSPAN flow.
The range is from 1 to 1023.
Configures the VRF to use instead of the global routing
table. You can use a VRF that you have specifically
configured or the default VRF.
Configures the ACL filter for packets in this ERSPAN
session. The ACL filter can be a MAC or an IP access-list.
(Optional)
Configures the IP time-to-live (TTL) value of the packets
in the ERSPAN traffic. Valid values are from 1 to 255.
The default value is 255.
(Optional)
Configures the IP Differentiated Services Code Point
(DSCP) value of the packets in the ERSPAN traffic. Valid
values are from 0 to 63. The default value is 0.
Enables the ERSPAN source session. By default, the
session is created in the shut state.
Note On Cisco Nexus 5000 Series switches, only two
ERSPAN source sessions can be running
simultaneously. On Cisco Nexus 5500 Series
switches, up to four source sessions can be
running simultaneously.
