Unicode Support Limitations
The following are Unicode support limitations:
• Usernames cannot contain Unicode characters.
• When defining policies for coherency, and so on, you cannot use Unicode characters in the
Description field.
• File server names cannot contain Unicode characters.
WAAS and Cisco IOS Interoperability
This section describes the interoperability of the WAAS software with the Cisco IOS features for a basic
WAAS deployment that uses WCCP-based interception and transparent transport and contains the
following topics:
• WAAS Support of the Cisco IOS QoS Classification Feature, page 1-11
• WAAS Support of the Cisco IOS NBAR Feature, page 1-12
• WAAS Support of the Cisco IOS Marking, page 1-13
• WAAS Support of the Cisco IOS Queuing, page 1-13
• WAAS Support of the Cisco IOS Congestion Avoidance, page 1-13
• WAAS Support of the Cisco IOS Traffic Policing and Rate Limiting, page 1-13
• WAAS Support of the Cisco IOS Signaling, page 1-13
• WAAS Support of the Cisco IOS Link-Efficiency Operations, page 1-13
• WAAS Support of the Cisco IOS Provisioning, Monitoring, and Management, page 1-14
• WAAS and Management Instrumentation, page 1-14
• WAAS and MPLS, page 1-15
Note The WAAS software does not support Cisco IOS IPv6 and Mobile IP.
We recommend that you use Cisco IOS Software Release 12.2 or later.
WAAS Support of the Cisco IOS QoS Classification Feature
You classify packets by using a policy filter (for example, using QPM) that is defined on the packets.
You may use the following policy filter properties:
• Source IP address or hostname—Supported under WAAS because the source IP address is preserved
by the WAAS device.
• Source TCP/UDP port (or port range)—Supported under WAAS because the source port is preserved
by the WAAS device.
• Destination IP address or hostname—Supported under WAAS because the destination IP is
preserved by WAAS. WAAS relies on interception at the data center for redirecting traffic to the peer
WAAS device.
• Destination TCP/UDP port (or port range)—Supported under WAAS because the destination IP is
preserved by WAAS. WAAS relies on interception at the data center for redirecting traffic to the peer
WAAS device.
