Nokia 7750 Basic Configuration

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.

To save configuration

A:7750-R1# admin save

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.
