Features
Configurable MAC address scaling that allows disabling MAC address learning on a VLAN to limit
•
the size of the MAC address table
• Cisco Discovery Protocol (CDP) Versions 1 and 2 for network topology discovery and mapping
between the switch and other Cisco devices on the network
• Link Layer Discovery Protocol (LLDP) and LLDP Media Endpoint Discovery (LLDP-MED) for
interoperability with third-party IP phones
LLDP media extensions (LLDP-MED) location TLV that provides location information from the
•
switch to the endpoint device
Support for CDP and LLDP enhancements for exchanging location information with video end
•
points for dynamic location-based content distribution from servers
Network Time Protocol (NTP) for providing a consistent time stamp to all switches from an external
•
source
Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses
•
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 16 simultaneous 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 Versions 1, 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
• 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
