MDAs are pluggable adapter cards that provide physical interface connectivity. MDAs are available in a variety of interface and density configurations. MDA modules differ by chassis. See the individual chassis guide and the individual MDA installation guides for more information about specific MDAs.
On the 7450 ESS-7/12, 7750 SR-7/12, and 7750 SR-12e, MDAs plug into IOMs. (MDA and MDA-XP modules plug into the IOM3-XP-C. MDA-e modules plug into the IOM4-e and IOM4-e-B, MDA-e-XP modules plug into the IOM5-e). Up to two MDAs can be provisioned on an IOM.
IMMs are designed with fixed integrated media cards, which may require provisioning, depending on the generation of the IMM.
MDA-a and MDA-aXP modules are used in the 7750 SR-a and the MDA-e and ISA2 modules are used in the 7750 SR-e chassis. Up to four MDAs can be provisioned for each IOM.
In all cases, the card slot and IOM or IMM card-type must be provisioned before an MDA can be provisioned. A preprovisioned MDA slot can remain empty without interfering with services on populated equipment. When an MDA is installed and enabled, the system verifies that the MDA type matches the provisioned type. If the parameters do not match, the MDA remains offline.
On the 7450 ESS-7/12, 7750 SR-7/12, and 7750 SR-12e platforms, MDA names in the CLI start with the letter 'm' (for example, m10-1gb-xp-sfp).
The following example displays the card, card-type, mda, and mda-type command usage in the 7750 SR-7:
A:SR7>config# card 1
A:SR7>config>card# card-type iom3
A:SR7>config>card# mda 1
A:SR7>config>card>mda# mda-type m48-1gb-xp-tx
A:SR7>config>card>mda# exit
A:SR7>config>card# mda 2
A:SR7>config>card>mda# mda-type m10-1gb-sfp
A:SR7>config>card>mda# exit
The following example displays the configuration:
A:SR7# admin display-config
. . .
----------------------------------------------
echo "Card Configuration "
#------------------------------------------
card 1
card-type iom3-xp-c
mda 1
mda-type m48-1gb-xp-tx
exit
mda 2
mda-type m10-1gb-sfp
exit
exit
----------------------------------------------
The 7750 SR-a4 and 7750 SR-a8 support only MDA-a and MDA-aXP modules, which are identified in the CLI with an ‟ma” prefix (for example, ma4-10gb-sfp+), or ‟max” prefix (for example, maxp10-10gb-sfp+). Likewise, the 7750 SR-1e, 7750 SR-2e, and 7750 SR-3e support only MDA-e modules, which are identified in the CLI with an ‟me” prefix, such as me1-100gb-cfp2.
The following example shows the card, card-type, mda, and mda-type command usage in the 7750 SR-1e:
A:SR1e>config# card 1
A:SR1e>config>card# card-type iom-e
A:SR1e>config>card# mda 1
A:SR1e>config>card>mda# mda-type me10-10gb-sfp+
A:SR1e>config>card>mda# exit
A:SR1e>config>card# mda 4
A:SR1e>config>card>mda# mda-type me1-100gb-cfp2
A:SR1e>config>card>mda# exit
The following example displays the configuration:
A:SR1e# admin display-config
. . .
----------------------------------------------
echo "Card Configuration"
#---------------------------------------------
card 1
card-type iom-e
mda 1
mda-type me10-10gb-sfp+
exit
mda 4
mda-type me1-100gb-cfp2
exit
exit
