Chapter 21 Configuring Cisco Intercompany Media Engine Proxy

Configuring Cisco Intercompany Media Engine Proxy

Creating ACLs for Cisco Intercompany Media Engine Proxy

To configure ACLs for the Cisco Intercompany Media Engine Proxy to reach the Cisco UCM server, perform the following steps.

The example command lines in this task are based on a basic (in-line) deployment. See Figure 21-6 on page 21-11for an illustration explaining the example command lines in this task.

 

Command

Purpose

 

 

 

Step 1

hostname(config)# access-list id extended permit tcp

Adds an Access Control Entry (ACE). An ACL is

 

any host ip_address eq port

made up of one or more ACEs with the same ACL

 

Example:

ID. This ACE provides access control by allowing

 

hostname(config)# access-list incoming extended

 

incoming access for Cisco Intercompany Media

 

permit tcp any host 192.168.10.30 eq 5070

 

Engine connections on the specified port.

 

 

 

 

In the ip_address argument, provide the real IP

 

 

address of Cisco UCM.

 

 

 

Step 2

hostname(config)# access-groupaccess-listin

Binds the ACL to an interface.

 

interface interface_name

 

 

Example:

 

 

hostname(config)# access-group incoming in interface

 

 

outside

 

 

 

 

Step 3

hostname(config)# access-list id extended permit tcp

Adds an ACE. This ACE allows the ASA to allow

 

any host ip_address eq port

inbound SIP traffic for Cisco Intercompany Media

 

Example:

Engine. This entry is used to classify traffic for the

 

hostname(config)# access-list ime-inbound-sip

 

class and policy map.

 

extended permit tcp any host 192.168.10.30 eq 5070

 

 

 

 

Note The port that you configure here must match

 

 

the trunk settings configured on Cisco UCM.

 

 

See the Cisco Unified Communications

 

 

Manager documentation for information

 

 

about this configuration setting.

 

 

 

Step 4

hostname(config)# access-list id extended permit tcp

Adds an ACE. This ACE allows the ASA to allow

 

ip_address mask any range range

outbound SIP traffic for Cisco Intercompany Media

 

Example:

Engine (in the example, any TCP traffic with source

 

hostname(config)# access-list ime-outbound-sip

 

as 192.168.10.30 and destination port range between

 

extended permit tcp 192.168.10.30 255.255.255.255

 

5000 and 6000). This entry is used to classify traffic

 

any range 5000 6000

 

 

for the class and policy map.

 

 

Note Ensure that TCP traffic between Cisco UCM

 

 

and the Cisco Intercompany Media Engine

 

 

server does not use this port range (if that

 

 

connection goes through the ASA).

 

 

 

Step 5

hostname(config)# access-list id permit tcp any host

Adds an ACE. This ACE allows the ASA to allow

 

ip_address eq 6084

traffic from the Cisco Intercompany Media Engine

 

Example:

server to remote Cisco Intercompany Media Engine

 

hostname(config)# access-list ime-traffic permit tcp

 

servers.

 

any host 192.168.10.12 eq 6084

 

 

 

 

 

Step 6

hostname(config)# access-list id permit tcp any host

Adds an ACE. This ACE allows the ASA to allow

 

ip_address eq 8470

traffic from the Cisco Intercompany Media Engine

 

Example:

server to the Bootstrap server for the Cisco

 

hostname(config)# access-list ime-bootserver-traffic

 

Intercompany Media Engine.

 

permit tcp any host 192.168.10.12 eq 8470
