Features
•
Directed unicast requests to a DNS server for identifying a switch through its IP address and its
corresponding hostname and to a TFTP server for administering software upgrades from a TFTP
server
Address Resolution Protocol (ARP) for identifying a switch through its IP address and its
•
corresponding MAC address
•
Unicast MAC address filtering to drop packets with specific source or destination MAC addresses
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 (supported on NNIs by default, can be
enabled on ENIs, not supported on UNIs)
Link Layer Discovery Protocol (LLDP) and LLDP Media Endpoint Discovery (LLDP-MED) for
•
interoperability with third-party IP phones
•
Support for the LLDP-MED location TLV that provides location information from the switch to the
endpoint device
•
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
•
•
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 (requires the cryptographic versions of the switch
software).
•
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
•
Out-of-band management access through the Ethernet management port to a PC
•
User-defined command macros for creating custom switch configurations for simplified deployment
across multiple switches
Support for metro Ethernet operation, administration, and maintenance (OAM) IEEE 802.1ag
•
Connectivity Fault Management (CFM), Ethernet Line Management Interface (E-LMI) on
customer-edge switches, and IEEE 802.3ah Ethernet OAM discovery, link monitoring, remote fault
detection, and remote loopback, and IEEE 802.3ah Ethernet OAM discovery, link monitoring,
remote fault detection, and remote loopback
Configuration replacement and rollback to replace the running configuration on a switch with any
•
saved Cisco IOS configuration file
•
Source Specific Multicast (SSM) mapping for multicast applications to provide a mapping of source
to allowing IGMPv2 clients to utilize SSM, allowing listeners to connect to multicast sources
dynamically and reducing dependencies on the application
CPU utilization threshold trap monitors CPU utilization.
