Wireshark - Cisco Catalyst 4500 Series Software Configuration Manual

Chapter 1 Product Overview
Web Content Communication Protocol (WCCP) Version 2 Layer 2 redirection enables Catalyst 4500
series switches to transparently redirect content requests to the directly connected content engines by
using a Layer 2 and MAC address rewrite. The WCCPv2 Layer 2 redirection is accelerated in the
switching hardware, and is more efficient than Layer 3 redirection using Generic Routing Encapsulation
(GRE). The content engines in a cache cluster transparently store frequently accessed content, and then
fulfills successive requests for the same content, eliminating repetitive transmissions of identical content
from the original content servers. It supports the transparent redirection of HTTP and non-HTTP traffic
with ports or dynamic services, such as Web caching, HTTPS caching, File Transfer Protocol (FTP)
caching, proxy caching, media caching, and streaming services. WCCPv2 Layer 2 redirection is
typically deployed for transparent caching at network edge, such as regional or branch sites. WCCPv2
Layer 2 redirection cannot be enabled on the same input interface with PBR or VRF-lite. ACL-based
classification for Layer 2 redirection is not supported.

Wireshark

Wireshark is supported only on Supervisor Engine 7-E, Supervisor Engine 7L-E, Supervisor Engine 8-E,
Note
and Catalyst 4500X.
Starting with Cisco IOS Release XE 3.3.0SG and the IP Base and Enterprise Services feature sets, the
Catalyst 4500 series switch supports Wireshark. This is a packet analyzer program, formerly known as
Ethereal that supports multiple protocols and presents information in a graphical and text-based user
interface. Wireshark is applied or enabled on an individual interface; global packet capture is not
supported.

XML-PI
eXtensible Markup Language Programmatic Interface (XML-PI) Release 1.0 leverages the Network
Configuration Protocol (NETCONF). It provides new data models that collect running configurations
and show command output down to the keyword level without requiring the technologies or external
XML-to-command line interface (CLI) gateways. XML-PI allows you to develop XML-based network
management applications to control any number of network devices simultaneously.
