XMAs are supported on the 7750 SR-1s/2s/7s/14s and 7950 XRS platforms. XMAs plug into XCMs. XCMs must be provisioned before an XMA can be provisioned with a type.
The XMA information must be configured before ports can be configured. After you configure the XCM, use the following CLI commands to provision XMAs.
A maximum of two XMAs can be configured on an XCM. The following example displays the card slot, card type, MDA slot, and MDA type command usage:
A:XRS20>config# card 1
A:XRS20>config>card# card-type xcm-x20
A:XRS20>config>card# mda 1
A:XRS20>config>card>mda# mda-type cx2-100g-cfp
A:XRS20>config>card>mda# power-priority-level 130
A:XRS20>config>card>mda# exit
A:XRS20>config>card# mda 2
A:XRS20>config>card>mda# mda-type cx20-10g-sfp
A:XRS20>config>card>mda# power-priority-level 135
A:XRS20>config>card>mda# exit
The following example displays the configuration:
A:XRS20# admin display-config

On the 7950 XRS, the show card state output displays an ‟x” in the name of the XMA and ‟cx” in the name of a C-XMA:
A:Dut-A# show card state
