SPAN-Related Feature Descriptions
The column headers in Table 11 are SPAN-related features or restrictions that can
affect the deployment of Cisco VoIP services. Each feature was discussed in earlier
sections of this document. The sections below provide summaries so that the table's
contents are clear.
Max SPAN Sessions
This column shows the maximum number of simultaneous SPAN sessions, port
monitor configurations, or snooping sessions that are supported on the switch. Many
of the switches have limitations on the number of sessions based on the type of traffic
being captured from the source ports (for example, ingress-only) or whether VLANs are
used as sources. Refer to the switch's documentation for details on these limitations.
SPAN
This column shows whether the switch supports some type of facility that allows
network traffic from one or more ports to be copied to a destination port. This can be
via SPAN, port monitoring, or snooping. Notice that all of the switches in
Table 11
support some sort of SPAN functionality. Some very small switches or highly
specialized switches do not offer this functionality, but they are not likely to be major
components in a contact center network, so they are not shown.

1 ERSPAN might work, but it has not been tested and therefore is not supported.
2 There is no hard limit for the number of port monitoring sessions that can be created. It is limited by the number
of ports on the switch.
