Basic Configuration

Renewing DCHP
– DHCP may lease addresses to clients indefinitely or for a
specific period of time. If the address expires or the switch is moved to another
network segment, you will lose management access to the switch. In this case, you
can reboot the switch or submit a client request to restart DHCP service via the CLI.
Web
– If the address assigned by DHCP is no longer functioning, you will not be
able to renew the IP settings via the web interface. You can only restart DHCP
service via the web interface if the current address is still available.
CLI
– Enter the following command to restart DHCP service.
Enabling Jumbo Frames
The switch provides more efficient throughput for large sequential data transfers by
supporting jumbo frames up to 10 KB for the Gigabit Ethernet ports. Compared to
standard Ethernet frames that run only up to 1.5 KB, using jumbo frames
significantly reduces the per-packet overhead required to process protocol
encapsulation fields.
Command Usage
• To use jumbo frames, both the source and destination end nodes (such as a
computer or server) must support this feature. Also, when the connection is
operating at full duplex, all switches in the network between the two end nodes
must be able to accept the extended frame size. And for half-duplex connections,
all devices in the collision domain would need to support jumbo frames.
• Enabling jumbo frames will limit the maximum threshold for broadcast storm
control to 64 packets per second. (See "Setting Broadcast Storm Thresholds" on
page 3-127.)
Command Attributes
Jumbo Packet Status
– Check the box to enable jumbo frames.
Web
– Click System, Jumbo Frames. Enable or disable support for jumbo frames,
and click Apply.
