Chapter 21 Configuring Cisco Intercompany Media Engine Proxy

Configuring Cisco Intercompany Media Engine Proxy

	Commands	Purpose

Step 6	hostname(config)# crypto ca authenticate trustpoint	Imports the certificate from local Cisco UCM.
	Example:	Where trustpoint is the trustpoint for the local Cisco
	hostname(config)# crypto ca authenticate	Where trustpoint is the trustpoint for the local Cisco
	local-ent-ucm	UCM.
		Paste the certificate downloaded from the local
		Cisco UCM. This certificate enables the ASA to
		validate the certificate that Cisco UCM sends in the
		TLS handshake.

Step 7	hostname(config)# tls-proxyproxy_name	Updates the TLS proxy for outbound connections.
	hostname(config-tlsp)# server trust-point	Where proxy_name is the name you entered in
	proxy_trustpoint	Where proxy_name is the name you entered in
	hostname(config-tlsp)# client trust-point	Step 1 of the task Creating the TLS Proxy.
	proxy_trustpoint	Where proxy_trustpoint for the server trust-point
	hostname(config-tlsp)# client cipher-suite	Where proxy_trustpoint for the server trust-point
	hostname(config-tlsp)# client cipher-suite	command is the name you entered in Step 4 of this
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1	command is the name you entered in Step 4 of this
	Example:	procedure.
	hostname(config)# tls-proxy local_to_remote-ent	Where proxy_trustpoint for the client trust-point
	hostname(config-tlsp)# server trust-point	Where proxy_trustpoint for the client trust-point
	local-ent-ucm	command is the name you entered in Step 2 of the
	hostname(config-tlsp)# client trust-point local-ent	task Creating Trustpoints and Generating
	hostname(config-tlsp)# client cipher-suite	Certificates.
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1	Certificates.
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1
		Note In this step, you are creating different
		trustpoints for the client and the server.

Step 8	hostname(config-tlsp)# exit	Exits from TLS Proxy Configuration mode.

Step 9	hostname(config)# tls-proxyproxy_name	Updates the TLS proxy for inbound connections.
	hostname(config-tlsp)# server trust-point	Where proxy_name is the name you entered in
	proxy_trustpoint	Where proxy_name is the name you entered in
	hostname(config-tlsp)# client trust-point	Step 5 of the task Creating the TLS Proxy.
	proxy_trustpoint	Where proxy_trustpoint for the server trust-point
	hostname(config-tlsp)# client cipher-suite	Where proxy_trustpoint for the server trust-point
	hostname(config-tlsp)# client cipher-suite	command is the name you entered in Step 2 of the
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1	command is the name you entered in Step 2 of the
	Example:	task Creating Trustpoints and Generating
	hostname(config)# tls-proxy remote_to_local-ent	Certificates.
	hostname(config-tlsp)# server trust-point local-ent	Where proxy_trustpoint for the client trust-point
	hostname(config-tlsp)# client trust-point	Where proxy_trustpoint for the client trust-point
	local-ent-ucm	command is the name you entered in Step 4 of this
	hostname(config-tlsp)# client cipher-suite	procedure.
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1	procedure.
	aes128-sha1 aes256-sha1 3des-sha1 null-sha1

Step 10	hostname(config-tlsp)# exit	Exits from TLS Proxy Configuration mode.

Step 11	hostname(config)# uc-imeuc_ime_name	Updates the Cisco Intercompany Media Engine
	hostname(config-uc-ime)# ucm address ip_address	Proxy for trunk-security-mode.
	trunk-security-mode secure	Where uc_ime_name is the name you entered in
	Example:	Where uc_ime_name is the name you entered in
	hostname(config)# uc-ime local-ent-ime	Step 1 of the task Creating the Cisco Intercompany
	hostname(config-uc-ime)# ucm address 192.168.10.30	Media Engine Proxy.
	trunk-security-mode secure	Media Engine Proxy.
	trunk-security-mode secure
		Only perform this step if you entered nonsecure in
		Step 3 of the task Creating the Cisco Intercompany
		Media Engine Proxy.

What to Do Next

Once you have configured the TLS within the enterprise, if necessary, configure off path signaling for an off path deployment. See (Optional) Configuring Off Path Signaling, page 21-30.
