• VLAN Settings: Two alternatives may show, depending upon the switch configuration. These
options are mutually exclusive.
• IEEE 802.1Q VLAN Settings: shows, by VLAN ID (PVID), which ports belong and
whether their egress packets are tagged or untagged.
• Port-Based VLAN Settings: shows which ports belong to each VLAN ID.
• TRUNK Status: shows the Trunk group, the ports that belong to the group and whether
trunking (Port Aggregation) is enabled for that group.
• Monitor Status: shows ports being monitored and whether this monitoring (sniffing) is of
ingress or egress traffic. Monitoring copies all traffic from the ports in question to the sniffer
port.
• Jumbo Frame: Oversized “Jumbo” (10240 byte) Ethernet frame support may be enabled or
disabled through the switch. If it is disabled, Jumbo frames are dropped.
• IEEE 802.1W Rapid Spanning Tree Protocol (RSTP) Setting: shows the key parameters used
in STP implementation. Bridge Priority determines how likely the switch is to become the root
switch. Max Age determines the time for which configuration information is kept. Hello Time
is the interval between sent configuration messages. Forward Delay is a value for time spent in
a discarding state before passing frames.
The Switch Status page displays the port settings for both 10/100 Mbps and 10/100/1000 Mbps
ports. To configure the ports, go to the Switch → Port Configuration page.
• ID: The port number on the switch
• Speed: Indicates the communication mode set for the port. The default setting for all ports is
Auto-negotiation (Auto). The possible entries are Auto-negotiation (Auto), 10 Mbps half
duplex (10M Half), 10 Mbps full duplex (10M Full), 100 Mbps half duplex (100M Half), 100
Mbps full duplex (100M Full), or Disable.
• Flow Control: Indicates whether Flow Control support is set for on (Enabled) or off
(Disabled). The default setting for all ports is enabled.
• Link Status: Indicates the current speed and duplex for the port. DOWN means no link.
The next part of the Switch Status page shows the Virtual Local Area Network (VLAN) status. A
VLAN enables specified ports on the same switch to be partitioned electronically into separate
broadcast domains. By using VLANs, users can group users by logical function (for example
Accounting or Engineering) instead of by physical location based upon the particular switch port
connection.
This page displays the port-based IEEE 802.1Q VLAN settings. The default VLAN setting is to
group all ports to belong to port-based VLAN 1. To configure user-defined VLAN groups, go to
the Switch> VLAN page.
