11.9 MS-SPRing VC4 Squelch Table
MS-SPRing VC4 squelch tables show VC4s that will be squelched for every isolated node.
The MS-SPRing Squelch Table window displays the following information:
•
•
•
•
•
MS-SPRing squelching is performed on VC4s that carry VC4 circuits only.
Note
11.10 IEEE 802.17 Resilient Packet Ring Circuit Display
Resilient Packet Ring (RPR), as described in IEEE 802.17, is a metropolitan area network (MAN)
technology supporting data transfer among stations interconnected in a dual-ring configuration. The
IEEE 802.17b spatially-aware sublayer amendment is not yet ratified but is expected to add support for
bridging to IEEE 802.17. Since the amendment is not yet ratified, no equipment is currently
IEEE 802.17b compliant. The RPR-IEEE for ONS 15454 ML-Series cards is based on the expected
IEEE 802.17b-based standard.
For more information about IEEE 802.17 RPR, refer to the Cisco ONS 15454 and
Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide, Release 8.0.
CTC provides a graphical representation (map) of IEEE 802.17 RPR circuits between ML-Series cards
with a list of the following information:

VC4 Number—Shows the MS-SPRing VC4 numbers. For two-fiber MS-SPRings, the number of
VC4s is half the MS-SPRing OC-N, for example, an STM-16 MS-SPRing squelch table will show
8 VC4s. For four-fiber MS-SPRings, the number of VC4s in the table is the same as the MS-SPRing
STM-N.
West Source—If traffic is received by the node on its west span, the MS-SPRing node ID of the
source appears. (To view the MS-SPRing node IDs for all nodes in the ring, click the Ring Map
button.)
West Dest—If traffic is sent on the node's west span, the MS-SPRing node ID of the destination
appears.
East Source—If traffic is received by the node on its east span, the MS-SPRing node ID of the source
appears.
East Dest—If traffic is sent on the node's east span, the MS-SPRing node ID of the destination
appears.
