Configuration Tasks

Configuring Relevant Interface (Serial/Ethernet)

To configure either the serial or Ethernet interface, use the following commands beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# interface type slot/port-adapter/port	Configures the physical interface (serial/Ethernet)
	[ethernet serial]	for transmitting multicast packets and enters
		interface configuration mode.
Step 2
	Router(config-if)# ip address ip-address mask	Assigns the IP address and subnet mask for the
	[secondary]	interface. The secondary keyword is optional. It
		specifies that the configured address is a secondary
		IP address. If this keyword is omitted, the
		configured address is the primary IP address.
Step 3
	Router(config-if)#ip pim {dense-mode sparse mode	Specifies Protocol Independent Multicast (PIM).
	sparse-dense-mode}	Whatever mode you choose should match all the
		interfaces in all the routers of your network.
Step 4
	Router(config-if)# no shutdown	Enables the interface.

Configuring Voice Ports in High-Density Voice Network Modules

Amultiflex trunk interface card (NM-HDV) in a high-density voice network module requires special voice-port configuration when connecting for T1/E1 operation. To configure a multiflex trunk interface card in a high-density voice network module, use the following commands beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# voice class permanent tag	Defines voice class for transmit-receive mode and
		enters voice class configuration mode.
Step 2
	Router(config-class)#signal timing oos timeout	Disables signaling loss detection. (Use the
	seconds disabled	disabled keyword for hoot and holler
		applications.)
Step 3
	Router(config-class)# signal keepalive number	Specifies the keepalive signaling packet interval in
		seconds. The valid range is from 1 to 65535.
Step 4
	Router(config-class)# exit	Exits voice class configuration mode.
Step 5
	Router(config)# voice-cardslot	Enters voice-card configuration mode and selects
		the card to configure. The slot argument is a value
		from 0 to 3 that identifies the physical slot in the
		chassis where the voice card is located.
Step 6
	Router(config-voicecard)# codec complexity {high	Specifies call density and codec complexity based
	medium}	on the codec standard you are using. For hoot and
		holler applications, the codec complexity must be
		high. Voice multicasting does not support medium
		complexity, which is the default.
Step 7
	Router(config-voicecard)# exit	Exits voice-card configuration mode.
