SROS Command Line Interface Reference Guide HDLC Command Set

ip access-group <listname> [in out]

Use the ip access-groupcommand to create an access list to be used for packets transmitted on or received from the specified interface. Use the no form of this command to disable this type of control.

Syntax Description

<listname>	Assigned IP access list name.
in	Enables access control on packets received on the specified interface.
out	Enables access control on packets transmitted on the specified interface.

Default Values

By default, these commands are disabled.

Command Modes

(config-interface)#	Interface Configuration Mode
	Valid interfaces include: Ethernet (eth 0/1), virtual PPP interfaces (ppp 1), virtual
	HDLC interfaces (hdlc 1), virtual Frame Relay sub-interfaces (fr 1.20), tunnel
	interfaces (tunnel 1), and VLAN interface (vlan 1).

When this command is enabled, the IP destination address of each packet must be validated before being passed through. If the packet is not acceptable per these settings, it is dropped.

Usage Examples

The following example sets up the unit to only allow Telnet traffic (as defined in the user-configured TelnetOnly IP access list) into the HDLC interface:

(config)#ip access-list extended TelnetOnly

(config-ext-nacl)#permit tcp any any eq telnet (config-ext-nacl)#int hdlc 1

(config-hdlc 1)#ip access-group TelnetOnly in
