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, refer to the “About Slots and Interfaces” section in the Hardware Installation Guide for the Cisco 4400 Series Integrated Services Routers .

Configuring the Interfaces

The following sections give examples of configuring the router interfaces:

Configuring GigabitEthernet Interfaces

SUMMARY STEPS

  • enable
  • configure terminal
  • interface GigabitEthernet 0/0/1
  • ip address ip address dhcp pool
  • negotiation auto
  • end

DETAILED STEPS

 

Command or Action
Purpose

Step 1

enable

 

Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

 

Router# configure terminal

Enters global configuration mode.

Step 3

interface GigabitEthernet slot / subslot / port
 

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

Configure 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

 

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

Assign an IP address to the GigabitEthernet interface.

  • 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

 

Router(config-if)# negotiation auto

Select the negotiation mode.

  • auto—Performs link autonegotiation.

Step 6

end

 

Router(config-if)# end

End the current configuration session and return to privileged EXEC mode.

Example: Configuring the Interfaces

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 2.

 
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

Example: Viewing a List of All Interfaces

In this example, two commands are used to show all the interfaces:

Router# show platform software interface summary
Interface IHQ IQD OHQ OQD RXBS RXPS TXBS TXPS TRTL
-----------------------------------------------------------------------------
* GigabitEthernet0/0/0 0 0 0 0 0 0 0 0 0
* GigabitEthernet0/0/1 0 0 0 0 0 0 0 0 0
* GigabitEthernet0/0/2 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
 
Interface IHQ IQD OHQ OQD RXBS RXPS TXBS TXPS TRTL
------------------------------------------------------------------------------------------* GigabitEthernet0/0/0 0 0 0 0 0 0 0 0 0
* GigabitEthernet0/0/1 0 0 0 0 0 0 0 0 0
* GigabitEthernet0/0/2 0 0 0 0 0 0 0 0 0
* GigabitEthernet0/0/3 0 0 0 0 0 0 0 0 0
* GigabitEthernet 0 0 0 0 0 0 0 0 0
 

Example: Viewing Information About an Interface

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
