Dell PowerConnect 5224 - Jumbo Frame

¡ Local, Radius — The switch attempts to authenticate the user first, and then a RADIUS server attempts to authenticate the user.
l Server IP Address — Identifies the IP address of the RADIUS server.
l Server Port Number — Identifies the User Datagram Protocol (UDP) port number used by the RADIUS server.
l Secret Text String — Specifies the text string that is shared between the switch and the RADIUS server.
l Number of Server Transmits — Specifies the number of request transmits to the RADIUS server before failure.
l Timeout for a reply (sec)— Specifies the number of seconds the switch waits for a reply from the RADIUS server before it resends the request.

Jumbo Frame
From the Jumbo Frame page, you can enable and disable jumbo frame support on the switch.
The switch provides more efficient large sequential data transfers by supporting jumbo frames up to 9000 bytes. Compared to standard Ethernet frames that
run only up to 1500 bytes, using jumbo frames significantly reduces the per-packet overhead required to process protocol encapsulation fields.
To use jumbo frames, both the source and destination end nodes (such as a computer or server) must support jumbo frames. In addition, 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. For half-duplex
connections, all devices in the collision domain must support jumbo frames.
To enable jumbo frame support on the switch, set the Jumbo Frame Support Status to Enabled.
NOTE: The local switch user database must be set up through the CLI by manually entering user names and passwords.
Command
Usage
authentication login {radius | local |
radius local | local radius}
Defines the login authentication method and precedence.
radius-server host host_ip_address
Specifies the RADIUS server IP address.
radius-server port port_number
Sets the RADIUS server UDP port number.
radius-server key key_string
SetstheRADIUSencryptionkey(upto20characters).
radius-server retransmit
number_of_retries
Sets the number of times the switch attempts to authenticate
logonaccessthroughtheRADIUSserver.(Therangeis1–30.)
radius-server timeout
number_of_seconds
Sets the number of seconds the switch waits for a reply before
resending a request. (The range is 1–65535.)
NOTICE: Enabling jumbo frames on the switch limits the maximum threshold for broadcast storm control to 64 packets per second.
