Port Configuration

RSPAN Limitations
The following limitations apply to the use of RSPAN on this switch:
•
RSPAN Ports – Only ports can be configured as an RSPAN source, destination, or uplink;
static and dynamic trunks are not allowed. A port can only be configured as one type of
RSPAN interface – source, destination, or uplink. Also, note that the source port and
destination port cannot be configured on the same switch.
•
Local/Remote Mirror – The destination of a local mirror session (created on the
Interface > Port > Mirror page) cannot be used as the destination for RSPAN traffic.
•
Spanning Tree – If the spanning tree is disabled, BPDUs will not be flooded onto the
RSPAN VLAN.
•
MAC address learning is not supported on RSPAN uplink ports when RSPAN is enabled on
the switch. Therefore, even if spanning tree is enabled after RSPAN has been configured,
MAC address learning will still not be re-started on the RSPAN uplink ports.
•
IEEE 802.1X – RSPAN and 802.1X are mutually exclusive functions. When 802.1X is
enabled globally, RSPAN uplink ports cannot be configured, even though RSPAN source
and destination ports can still be configured. When RSPAN uplink ports are enabled on the
switch, 802.1X cannot be enabled globally.
•
Port Security – If port security is enabled on any port, that port cannot be set as an RSPAN
uplink port, even though it can still be configured as an RSPAN source or destination port.
Also, when a port is configured as an RSPAN uplink port, port security cannot be enabled
on that port.
Parameters
These parameters are displayed:
•
Session – A number identifying this RSPAN session. (Range: 1)
Only one mirror session is allowed, including both local and remote mirroring. If local mirroring
is enabled (see
“Configuring Local Port Mirroring”
on page 705), then no session can be
configured for RSPAN.
•
Operation Status – Indicates whether or not RSPAN is currently functioning.
•
Switch Role – Specifies the role this switch performs in mirroring traffic.
•
None – This switch will not participate in RSPAN.
•
Source - Specifies this device as the source of remotely mirrored traffic.
•
Intermediate - Specifies this device as an intermediate switch, transparently passing
mirrored traffic from one or more sources to one or more destinations.
•
Destination - Specifies this device as a switch configured with a destination port which is
to receive mirrored traffic for this session.
•
Remote VLAN – The VLAN to which traffic mirrored from the source port will be flooded. The
VLAN specified in this field must first be reserved for the RSPAN application using the VLAN >
Static page (see
•
Uplink Port – A port on any switch participating in RSPAN through which mirrored traffic is
passed on to or received from the RSPAN VLAN.
Only one uplink port can be configured on a source switch, but there is no limitation on the
number of uplink ports
configured on an intermediate or destination switch.
