Security
The AGM provides the same security to voice and video networks that is available for data networks.
The AGM supports the optional Cisco IOS Software Firewall Feature Set, Cisco IOS Intrusion Detection
Service (IDS), IP Security (IPsec) with data encryption standard (DES), and Triple DES (3DES).
Hardware encryption using the onboard encryption accelerator provides significantly higher
performance than software-based encryption, and frees processor capacity for other services.
The following encryption features are supported:
• 56-bit DES encryption using Cipher Block Chaining (CBC) mode
• 168-bit 3DES encryption using CBC mode
• MD5 and SHA-1 hashing, including support for the HMAC transform with IPSec AH and ESP
• Support for Diffie-Hellman key exchange
• RSA and DSA public key signature and verification (when implemented by IOS IPSec Crypto
Engine)
QoS
The AGM can identify user applications, such as voice or multicast video, and classify traffic with the
appropriate priority levels. QoS policies are enforced using Layer 2 and 3 information such as 802.1p
and IP precedence. The AGM queues employ weighted random early detection (WRED) and weighted
round-robin (WRR) to ensure that QoS is maintained as packets traverse the network.
To ease the deployment of QoS, the AGM supports Cisco QoS Policy Manager (QPM). QPM is a
complete policy management tool that enables provisioning of end-to-end differentiated services across
network infrastructures with converged voice, video, and data applications. The combination of QPM
and CiscoWorks Service Management Solution enables network administrators to adjust service levels
in accordance with defined QoS policies. The end result is network-wide intelligent, and consistent QoS
that enables performance protection for voice applications while reducing costs for growing networks.
Resiliency
The AGM provides the following tools to enhance the resiliency of networks:
• SRS Telephony provides resiliency for IP phones when they lose connectivity with the Cisco Call
Manager (For complete information on the feature, go to the following url:

• HSRP provides resiliency for IP packets
• BRI backup provides resiliency for WAN connections
