Slot and Subslot Configuration

Slot and Subslot Configuration

This chapter contains information on slots and subslots. Slots specify the chassis slot number in your router and subslots specify the slot where the service modules are installed.

For further information on the slots and subslots, see the “About Slots and Interfaces” section in the Hardware Installation Guide for the Cisco 4000 Series Integrated Services Routers.

The following section is included in this chapter:

Configuring the Interfaces

The following sections describe how to configure Gigabit interfaces and also provide examples of configuring the router interfaces:

Configuring Gigabit Ethernet Interfaces

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    interface GigabitEthernet slot/subslot/port

    4.    ip address ip-address mask [secondary] dhcp pool

    5.    negotiation auto

    6.    end


DETAILED STEPS
     Command or ActionPurpose
    Step 1enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    Enter your password if prompted.

     
    Step 2configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3interface GigabitEthernet slot/subslot/port


    Example:
    Router(config)# interface GigabitEthernet 0/0/1
     

    Configures a GigabitEthernet interface.

    • GigabitEthernet—Type of interface.

    • slot—Chassis slot number.

    • /subslot—Secondary slot number. The slash (/) is required.

    • /port—Port or interface number. The slash (/) is required.

     
    Step 4ip address ip-address mask [secondary] dhcp pool


    Example:
    Router(config-if)# ip address 10.0.0.1 255.255.255.0 dhcp pool
     

    Assigns an IP address to the GigabitEthernet

    • ip address ip-address—IP address for the interface.

    • mask—Mask for the associated IP subnet.

    • secondary (optional)—Specifies that the configured address is a secondary IP address. If this keyword is omitted, the configured address is the primary IP address.

    • dhcp—IP address negotiated via DHCP.

    • pool—IP address autoconfigured from a local DHCP pool.

     
    Step 5negotiation auto


    Example:
    Router(config-if)# negotiation auto
     

    Selects the negotiation mode.

    • auto—Performs link autonegotiation.

     
    Step 6end


    Example:
    Router(config-if)# end
     

    Ends the current configuration session and returns to privileged EXEC mode.

     

    Configuring the Interfaces: Example

    The following example shows the interface gigabitEthernet command being used to add the interface and set the IP address. 0/0/0 is the slot/subslot/port. The ports are numbered 0 to 3.

    Router# show running-config interface gigabitEthernet 0/0/0
    Building configuration...
    Current configuration : 71 bytes
    !
    interface gigabitEthernet0/0/0
    no ip address
    negotiation auto
    end
     
    Router# configure terminal
    Enter configuration commands, one per line. End with CNTL/Z.
    Router(config)# interface gigabitEthernet 0/0/0

    Viewing a List of All Interfaces: Example

    In this example, the show platform software interface summary and show interfaces summary commands are used to display all the interfaces:

    Router# show platform software interface summary

    Viewing Information About an Interface: Example

    The following example shows how to display a brief summary of an interface's IP information and status, including the virtual interface bundle information, by using the show ip interface brief command:

    Router# show ip interface brief
    Interface              IP-Address      OK?  Method  Status                 Protocol
    GigabitEthernet0/0/0    10.0.0.1       YES  manual  down                   down
