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.
Configuring Support for Jumbo Frames
The switch provides more efficient throughput for large sequential data
transfers by supporting jumbo frames up to 9000 bytes. 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.
Command Attributes
• Jumbo Packet Status – Configures support for jumbo frames.
