For consistency across platforms, XMAs are modeled in the system as MDAs, and unless specified otherwise, the term MDA is used generically in this document to refer to both MDAs and C-XMA/XMAs. When the term XMA is used, it refers to both XMAs and C-XMAs unless specified otherwise.
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
