Cisco ME 3800X and 3600X Switch Software Configuration Guide
OL-23400-01
Chapter 1 Overview
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.
