Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches
Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 2 Preparing AXSM Lines for Communication
General AXSM Provisioning Procedures
The AXSM card support, whether intracard or intercard, is called out in Table 2-1 on page 2-1.
Intracard and intercard APS line redundancy is discussed in greater detail in the “Managing Redundant
APS Lines” section of the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.
The sections that follow briefly describe how to configure these intracard and intercard APS lines.
• Adding Intracard APS Lines
• Adding Intercard APS Lines
Adding Intracard APS Lines
Use the following procedure to establish redundancy between two lines on the same card.
Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.
Step 2 If you have not done so already, bring up the working line as described in the “Bringing Up Lines”
section, which appears earlier in this chapter.
Step 3 Enter the addapsln command as follows:
addapsln < workingIndex > < protectIndex > < archmode >
Replace <workingIndex> with the location of the working line using the format slot.bay.line. Replace
<protectIndex> with the location of the protection line, using the same format used for the working line.
Note For intracard redundancy, the working index and protection index must specify ports on the same
card, so the slot and bay number for the working and protection index will always match.
Replace <archmode> with the option number that selects the automatic protection switching (APS)
architecture mode you want to use. Table 2-6 shows the option numbers and the architecture modes they
select.
Table 2-6 APS Line Architecture Modes
Option Description
1 Selects the following APS protocol signaling standards (transmission on both working
and protection lines):
• 1+1 Bellcore GR-253 APS
• ITU-T G783 Annex A
2 Selects 1:1 Bellcore GR-253 APS protocol signaling (transmission on either the
working line or the protection line) for intracard APS.
3 Selects 1+1 ITU-T G.783 AnnexB APS protocol signaling (transmission on both
working and protection lines).
4 Selects 1+1 Y-cable signaling without K1 and K2.
Note This option is not supported.
5 Selects 1+1 straight cable signaling without K1 and K2.
Note This option is not supported.
