VSAN as a SPAN Source
When a VSAN as a source is specified, then all physical ports and PortChannels in that VSAN are
included as SPAN sources. A TE port is included only when the port VSAN of the TE port matches the
source VSAN. A TE port is excluded even if the configured allowed VSAN list may have the source
VSAN, but the port VSAN is different.
You cannot configure source interfaces (physical interfaces, PortChannels, or sup-fc interfaces) and
source VSANs in the same SPAN session.
Guidelines to Configure VSANs as a Source
The following guidelines apply when configuring VSANs as a source:
•
Traffic on all interfaces included in a source VSAN is spanned only in the ingress direction.
• When a VSAN is specified as a source, you will not be able to perform interface-level SPAN
configuration on the interfaces that are included in the VSAN. Previously-configured SPAN-specific
interface information is discarded.
•
If an interface in a VSAN is configured as a SPAN source, you will not be able to configure that
VSAN as a source. You must first remove the existing SPAN configurations on such interfaces
before configuring VSAN as a source.
•
Interfaces are only included as sources when the port VSAN matches the source VSAN. displays a
configuration using VSAN 2 as a SPAN source:
–
All ports in the switch are in VSAN 1 except fc1/1.
– Interface fc1/1 is the TE port with port VSAN 2. VSANs 1, 2, and 3 are configured in the
allowed list.
–
VSAN 1 and VSAN 2 are configured as SPAN sources.

For the configuration shown in Figure 30-4 , the following apply:
•
VSAN 2 as a SPAN source includes only the TE port fc1/1 that has port VSAN 2.
