Layer 2 Switching Features; Ip Services - 3Com 3CRWX120695A Installation And Basic Configuration Manual

16 C 1: WX S O
HAPTER WITCH VERVIEW
Software and configuration management—You can store multiple
software images and configuration files in the WX switch's nonvolatile
storage.
Web Manager—Web Manager is a Web-based application for
configuring and managing a single WX switch through a Web
browser. Web Manager creates a secure connection by using
Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS).
Layer 2 Switching Spanning Tree Protocol (STP)—MSS is 802.1D-compatible and
Features supports Per-VLAN Spanning Tree (PVST+). PVST+ allows a separate
spanning tree in each virtual LAN (VLAN). Optional fast convergence
features allow you to quickly resume traffic forwarding after a
topology change.
Load-sharing port groups—You can configure multiple physical ports
into a single logical link for traffic load sharing and physical link
redundancy.
Virtual LANs (VLANs)—MSS supports logical segmentation of a
switch's ports into separate Layer 2 collision domains. A port can be a
member of one or more VLANs. Each VLAN can have its own IP
interface. MSS supports the 802.1Q tag format.
Internet Group Management Protocol (IGMP) snooping for multicast
containment—The WX switch can learn about the multicast sources
and receivers in the network and restrict forwarding for a multicast
group to the users for that group. IGMPv1 and IGMPv2 are supported.

IP Services

IP interfaces—You can configure an IP interface for each VLAN.
IP ping and traceroute—You can test IP connectivity between the WX
switch and other devices.
Domain Name Service (DNS)—You can configure the switch to use
DNS servers for name resolution. You also can configure a default
domain name to append to hostnames.
Network Time Protocol (NTP)—A WX switch can sets its time and date
by polling an NTP server.
System log—A WX generates log messages to log system events. The
log messages are stored locally and also can be exported to syslog
servers.
Simple Network Management Protocol (SNMP)—A WX switch can be
configured to generate SNMP traps for major system events.
