Chapter: 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 Cisco 1100 Terminal Server Gateway .

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 Action Purpose

Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

interface 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 4

ip 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 5

negotiation auto

Example:


Router(config-if)# negotiation auto

Selects the negotiation mode.

  • auto—Performs link autonegotiation.

Step 6

end

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
  Interface                 IHQ  IQD  OHQ  OQD  RXBS  RXPS  TXBS  TXPS  TRTL
-----------------------------------------------------------------------------

* GigabitEthernet0/0/1        0    0    0    0     0     0     0     0     0

* GigabitEthernet0/0/3        0    0    0    0     0     0     0     0     0
* GigabitEthernet0            0    0    0    0     0     0     0     0     0



Router# show interfaces summary
   *: interface is up
 IHQ: pkts in input hold queue     IQD: pkts dropped from input queue
 OHQ: pkts in output hold queue    OQD: pkts dropped from output queue
 RXBS: rx rate (bits/sec)          RXPS: rx rate (pkts/sec)
 TXBS: tx rate (bits/sec)          TXPS: tx rate (pkts/sec)
 TRTL: throttle count

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
GigabitEthernet0/0/1    unassigned     YES  NVRAM   administratively down  down
GigabitEthernet0/0/2    10.10.10.1     YES  NVRAM   up                     up
GigabitEthernet0/0/3    8.8.8.1        YES  NVRAM   up                     up
GigabitEthernet0        172.18.42.33   YES  NVRAM   up                     up
