Bridge and VLAN Configuration

This configuration sets up two bridges (brlan0 and brlan1) and two VLANs (vlan1000 and vlan2000) with assigned ports. The GigabitEthernet ports are associated with their respective bridges and VLANs.

Enabling Configuration Mode

1. Enter privileged EXEC mode by typing enable.

2. Enter global configuration mode with configure terminal.

Bridge Configuration

3. Create and configure brlan0 and brlan1 bridges:

   bridge brlan0
       no shutdown
   end
   
   bridge brlan1
       no shutdown
   end
   

   These commands create and activate the brlan0 and brlan1 bridges.

VLAN Configuration

4. Create and configure two VLANs, vlan1000 and vlan2000:

    vlan 1000
        name vlan1000
    end
   
    vlan 2000
        name vlan2000
    end
   

   These commands create VLANs with the names "vlan1000" and "vlan2000."

Port Configuration

5. Rename and configure GigabitEthernet ports and associate them with the respective bridges and VLANs:

   • Gig0 is associated with brlan0 and vlan1000:

     flush enx3c8cf8f943a2
     rename if enx3c8cf8f943a2 if-alias Gig0
     
     interface Gig0
         bridge group brlan0
         switchport access vlan vlan1000
         no shutdown
     end
     

   • Gig1 is associated with brlan0 and vlan1000:

     flush enx00249b119cef
     rename if enx00249b119cef if-alias Gig1
     
     interface Gig1
         bridge group brlan0
         switchport access vlan vlan1000
         no shutdown
     end
     

   • Gig2 is associated with brlan1 and vlan2000:

     flush enx9cebe81be18a
     rename if enx9cebe81be18a if-alias Gig2
     
     interface Gig2
         bridge group brlan1
         switchport access vlan vlan2000
         no shutdown
     end
     

   • Gig3 is associated with brlan1 and vlan2000:

     flush enx8cae4cdb5f8e
     rename if enx8cae4cdb5f8e if-alias Gig3
     
     interface Gig3
         bridge group brlan1
         switchport access vlan vlan2000
         no shutdown
     end
     

   These configurations rename the interfaces for clarity and associate them with their respective bridges and VLANs.

Saving and Exiting Configuration

6. To save your configuration, use the write memory or copy running-config startup-config command.

7. Exit configuration mode with exit.

Full Configuration

Here's the complete configuration for your reference:

enable
configure terminal

bridge brlan0
    no shutdown
end

bridge brlan1
    no shutdown
end

vlan 1000
    name vlan1000
end

vlan 2000
    name vlan2000
end

flush enx3c8cf8f943a2
rename if enx3c8cf8f943a2 if-alias Gig0

interface Gig0
    bridge group brlan0
    switchport access vlan vlan1000
    no shutdown
end

flush enx00249b119cef
rename if enx00249b119cef if-alias Gig1

interface Gig1
    bridge group brlan0
    switchport access vlan vlan1000
    no shutdown
end

flush enx9cebe81be18a
rename if enx9cebe81be18a if-alias Gig2

interface Gig2
    bridge group brlan1
    switchport access vlan vlan2000
    no shutdown
end

flush enx8cae4cdb5f8e
rename if enx8cae4cdb5f8e if-alias Gig3

interface Gig3
    bridge group brlan1
    switchport access vlan vlan2000
    no shutdown
end

This full configuration establishes two bridges, two VLANs, and associates GigabitEthernet ports with their respective bridges and VLANs. Adjust the configuration as needed for your network setup.
