Switch Commands

This chapter describes commands used to configure the switch port on the Cisco 3800 system. The switch port is a new interface type that supports a switch engine device. A switch interface is not associated with any physical port; rather, it represents a whole engine. It is a virtual device created for network management and configuration. It is considered a Layer 3 protocol termination point to Cisco IOS. A switch interface can be assigned a Layer 3 address and runs Layer 3 host protocols. For the physical ports, the only new switch port introduced at the Cisco IOS software interface level is S0.

Commands are listed in Table 7-1, Table 7-2, Table 7-3, and Table 7-4 and are described in detail later in this chapter

Table  7-1: Commands to Configure the Switch

show call-controller statistics	Show statistics about calls.

Table  7-3: Command to Clear the Switch

Command	Description
clear controller switch	Clear statistics about calls.

Table  7-4: Commands to Debug the Switch

Command	Description
debug switch connection	Enable debugger output of switch connection establishment and teardown.
debug switch setup	Enable debugger output for switch call setup and clear.
debug switch signaling	Enable debugger output for switch call signaling messages
debug switch timers	Enable debugger output for timer operation in switch call setup.
debug switch verbose	Enable detailed debugger messages for switch call setup and signaling.

Quick Reference of Switch Commands and Modes

Figure 7-1: Switch Commands with Modes and Prompts

Entering Privileged Mode

To enter privileged mode, characterized by the # prompt, enter the following command:

>enable exec
Freezer#

To enter global configuration mode, characterized by the (conf)# prompt, enter the following command from privileged exec mode:

Freezer# config term
Freezer(conf)#

clear controller switch

Clears statistics about calls, such as the number of calls handled and the number of calls failed.

Freezer# clear controller switch 0 call-statistics

connect frame relay

From global configuration mode, enter the connect frame relay command to establish a switched Frame Relay connection. Use the no form of this command to break the connection.

Freezer(conf)# connect source-address destination-address [class ]
Freezer(conf)# no connect source-address destination-address [class]

Syntax Description

source-address, destination-address	Addresses consist of the following: · Topology address. · Source or destination hostname. · Standard description of interface type--serial or source. · Channel, serial channel (DLCI), or switch channel (connection ID and session number tag, 6-126). Depends on encapsulation of the interface; serial is for encaps frame-relay, switch is for encaps ftc-trunk.
class	Name of Frame Relay media class--for example, slow-pvc.

Example

The following command connects serial Frame Relay to remote serial Frame Relay:

Freezer(conf)# connect serial0/1 dlci 100 hostname Europa serial0/3 dlci 300 class slow-pvc

connect voice

The connect voice command is used to establish a switched voice connection. Use the no form of this command to break a switched voice connection.

Freezer(conf)# connect source-address destination-address { active | passive }
Freezer(conf)# no connect source-address destination-address { active | passive }

Syntax Description

source-address destination-address	Addresses consist of the following: · Topology address. · Source or destination hostname. · Standard description of source and destination interface type, serial or source. · Channel, serial channel (DLCI), or switch channel (connection ID and session number tag 6-126). Depends on encapsulation of the interface; serial is for encaps frame-relay, switch is for encaps ftc-trunk.
active	Set the node to active when you want to initiate the connection.
passive	Set the node to passive when you want the node to wait for contact.

---

Note Source interface type must be a voice dial-peer-tag; destination can be a voice dial-peer or an FTC trunk connection ID.

---

Example

The following command connects voice to remote voice:

Freezer(conf)# connect voice 10 38002 voice51 active

debug switch connection

Use the debug switch connection command to enable debugger output for switch information about connection establishment and teardown. Use the no form fo this command tp disable debugger output for switch information about connection estabnlishment and teardown.

Freezer# debug switch connection
Freezer# no debug switch connection

debug switch setup

Use the debug switch setup command to enable debugger output for switch call setup and clear. Use the no form of this command to disable debugger output for switch call setup and clear.

Freezer# debug switch setup
Freezer# no debug switch setup

debug switch signaling

Use the debug switch signaling command to turn on debug output for switch call signaling messages. Use the no form of this command to disable the switch timer debugger output.

---

Note This flag is not turned on by the debug all command.

---

Freezer# debug switch signaling
Freezer# no debug switch signaling

debug switch timers

Use the debug switch timers command to turn on debug output for timer operation in switch call setup and signaling. Use the no form of this command to disable the switch timer debugger output.

---

Note This flag is not turned on by the debug all command.

---

Freezer# debug switch timers
Freezer# no debug switch timers

debug switch verbose

Use the debug switch verbose command to turn on more detailed debug messages for switch call setup and signaling. Use the no form of this command to disable the debug messages for switch call setup and signaling.

Freezer# debug switch verbose
Freezer# no debug switch verbose

---

Note This flag is not turned on by the debug all command.

---

show call-controller call

Displays all Q2931 connections, or a single connection in detail when youinclude an optional parameter.

Freezer# show call-controller call [ connection-number ]

Syntax Description

detailed	If specified, a detailed listing displays.
connection-number	If specified, a detailed listing of the specific connection displays. This number is assigned by the system and is a current connection ID from 1-252.

show call-controller statistics

Use the show call-controller statistics command to show statistics about calls, such as the number of calls handled and the number of calls that failed.

Freezer# show call-controller statistics

show connection-table

Displays all connections in a given table, or the single connection specified in detail if optional parameters are provided.

Freezer# show connection-table [ detailed connection-number ]

Syntax Description

detailed	If specified, a detailed listing displays.
connection-number	If specified, a detailed listing of the specific connection displays. This number is assigned by the system.
