Catalyst 3750 SwitchSoftware Configuration Guide
OL-8550-09
Chapter1 Overview
Features
•Source Specific Multicast (SSM) mapping for multicast applications provides a mapping of source
to group, allowing listeners to connect to multicast sources dynamically and reduces dependencies
on the application
•Support for Enhanced Interior Gateway Routing Protocol (EIGRP) IPv6 to utilize IPv6 transport,
communicate with IPv6 peers, and advertise IPv6 routes
•Support for these IP services, making them VRF aware so that they can operate on multiple routing
instances: HSRP, ARP, SNMP, IP SLA, TFTP, FTP, syslog, traceroute, and ping
•Configuration logging to log and to view changes to the switch configuration
•Unique device identifier to provide product identification information through a show inventory
user EXEC command display
•In-band management access through the device manager over a Netscape Navigator or Microsoft
Internet Explorer browser session
•In-band management access for up to 16simultaneous Telnet connections for multiple CLI-based
sessions over the network
•In-band management access for up to five simultaneous, encrypted Secure Shell (SSH) connections
for multiple CLI-based sessions over the network
•In-band management access through SNMP Versions1, 2c, and 3 get and set requests
•Out-of-band management access through the switch console port to a directly attached terminal or
to a remote terminal through a serial connection or a modem
•Secure Copy Protocol (SCP) feature to provide a secure and authenticated method for copying
switch configuration or switch image files (requires the cryptographic version of the software)
•Configuration replacement and rollback to replace the running configuration on a switch with any
saved Cisco IOS configuration file
•On the Catalyst 3750G Integrated Wireless LAN Controller Switch only, an integrated
Catalyst 3750 switch and Cisco 4400 series wireless LAN controller that supports up to 25 or 50
lightweight access points
•The HTTP client in Cisco IOS supports can send requests to both IPv4 and IPv6 HTTP server, and
the HTTP server in Cisco IOS can service HTTP requests from both IPv4 and IPv6 HTTP clients
•Simple Network and Management Protocol (SNMP) can be configured over IPv6 transport so that
an IPv6 host can send SNMP queries and receive SNMP notifications from a device running IPv6
•IPv6 stateless autoconfiguration to manage link, subnet, and site addressing changes, such as
management of host and mobile IP addresses
•Disabling MAC address learning on a VLAN
•DHCP server port-based address allocation for the preassignment of an IP address to a switch port.
•Wired location service sends location and attachment tracking information for connected devices to
a Cisco Mobility Services Engine (MSE)
•CPU utilization threshold trap monitors CPU utilization
•LLDP-MED network-policy profile time, length, value (TLV) for creating a profile for voice and
voice-signalling by specifying the values for VLAN, class of service (CoS), differentiated services
code point (DSCP), and tagging mode
•Support for including a hostname in the option 12 field of DHCPDISCOVER packets. This provides
identical configuration files to be sent by using the DHCP protocol
