The Processor Switching Module

Initial APS specification consists of the working and protection slot and line and the mode for APS. After the initial APS specification, you can configure additional APS parameters, give commands for switching lines, and display the APS configuration. The CiscoView application and CLI provide access to the APS feature. For detailed descriptions of the CLI commands, see the Cisco MGX 8850 Wide Area Edge Switch Command Reference. Note that APS is available for only the “B” versions of the SONET cards—SMLR-1-622/B, and so on. The applicable CLI commands are:

•

•

•

•

•

addapsln to specify the lines and mode for APS

cnfapsln to modify the following details of APS operation:

—error thresholds

—wait period before the PXM restores the working line after errors clear

—unidirectional or bidirectional switchover, which specifies whether one or both directions of a line are switched when the criteria for a hard or soft failure are met for one direction

—revertive recovery, where the working line automatically returns to operation after errors clear and any wait period has elapsed

—enable use of K1 and K2 bytes in the line-level frame for equipment at both ends to exchange APS-related information

delapsln to delete the APS configuration

dspapsln to display the configuration for an APS-configured line switchapsln to issue commands for line switching that:

—clear previous user requests

—lock out (block) line switching

—manually switch to the protection line if the following are true: no errors exist, the working line is active, and your request has an equal or higher priority than the last switch request.

—force a line switch regardless of existing errors the following are true: the working line is active and your request has an equal or higher priority than the last switch request.

—switch all traffic to either the working lines or protection lines so you can remove a card (applies to only the currently supported configuration of 1+1 mode on two uplink cards)

To specify APS, use the following syntax:

addapsln <workline> <workingslot> <protectionline> <protectionslot> <archmode>

where workline and workingslot identify the line and slot of the APS working line, and protectionline and protectionslot identify the protection line and slot. According to GR-253, the archmode identifies the type of APS operation. The mode definition includes:

11+1 on one back card

21+1 on two back cards

31:1

4Annex B

Currently, the only supported mode is 1+1 with two uplink cards (mode=2). With 1+1 APS, both the working line and the protection line carry duplicate data even though no error threshold has been exceeded or line break has occurred. This mode requires that two standard cables (rather than a Y-cable) connect at two ports on the equipment at the opposite end. With the two-card implementation, workline must be the same as protectionline.
