Nokia 7750 SR getting started and basic configuration
Nokia 7750 SR router run TiMOS operating system originally developed by Alcatel.
For this lab I am using TiMOS version 12.0 R6.

Once you login using the default username and password admin/admin. Let's set the hostname.

Completed.
One of the most important steps after SR bootup, we need to provision the cards and mda
*A:7750-R1# show card state
===============================================================================
Card State
===============================================================================
Slot/ Provisioned Type Admin Operational Num Num Comments
Id Equipped Type (if different) State State Ports MDA
-------------------------------------------------------------------------------
1 (not provisioned) up unprovisioned 0
iom3-xp-b
A sfm4-12 up up Active
B sfm4-12 up down Standby
(not equipped)
===============================================================================
As we can see the card iom3-xp-b is admin up but operational state shows that it is unprovisioned. So we will provision this card.
*A:7750-R1# configure card 1 card-type "iom3-xp-b"
Now let's configure the MDA. After entering mda1 mda-type hit the Tab or ? key to see available options. The option that works for me in this lab scenario is appearing in bold.
*A:7750-R1>config>card# mda 1 mda-type
- mda-type <mda-type>
- no mda-type
<mda-type> : isa-aa|isa-bb|isa-tms|isa-tunnel|isa-video|m1-10gb|

m8-oc12/3-sfp|m8-oc3-sfp|vsm-cca|vsm-cca-xp
*A:7750-R1>config>card# mda 1 mda-type "m5-1gb-sfp-b"
To verify the configuration (not just for the card we just did in the steps above) the info command will show the configuration applied within the context.
i*A:7750-R1>config>card# info ---------------------------------------------- card-type iom3-xp-b mda 1 mda-type m5-1gb-sfp-b no shutdown exit no shutdown ----------------------------------------------
and we are done with provisioning the card. Now let's take a look at the card status.
Tip! Without going back to the user mode by typing exit we can run any command with the / like we prepend the do to any command in Cisco and run in Juniper.
*A:7750-R1>config>card# /show card state
===============================================================================
Card State
===============================================================================
Slot/ Provisioned Type Admin Operational Num Num Comments
Id Equipped Type (if different) State State Ports MDA
-------------------------------------------------------------------------------
1 iom3-xp-b up up 2
1/1 m5-1gb-sfp-b up up 5
A sfm4-12 up up Active
B sfm4-12 up down Standby
(not equipped)
===============================================================================
We can now see that the card on slot 1 iom3-xp-b has an operational state of up and the MDA on slot id 1/1 is also in up state.
Once the cards are provisioned we will be able to see the usable interfaces.

Some useful commands
admin display-config : to display the running configuration
show card or show card state shows a summary of all the available cards, but not necessary in active or in operation.
show router route-table display the routing table
show port to check the interface status.
