2-68 Sun StorEdge 5310 NAS Troubleshooting Guide • December 2004
2. To view the current negotiated rate: Enter "em show all". The name of each NIC
and current speed, duplex and link status is displayed.
3. To force a particular rate (and disable auto-negotiation): enter “em set <NICname>
duplex=<duplex> speed=<speed>”. Replace <NICname> with the name of the
NIC found in the above show command, <duplex> with either “full” or “half”,
and <speed with either “10”, “100” or “1000”. Be sure to force the same settings on
the switch.
For example, to set the second NIC card to 100baseT full duplex:
PROMPT> em show all
emc1: 100Mb/s FULL-DUPLEX, Link is UP
emc2: 10Mb/s HALF-DUPLEX, Link is UP
PROMPT> em set emc2 duplex=full speed=100
Here, we checked the speed and duplex, found NIC emc2 to be running at 10Mb/s
half duplex, then forced NIC emc2 to 100Mb/s full duplex.
Default gateway changes without user input.
Under certain circumstances, the default gateway on StorEdge can be modified via
ICMP. Typically, this is an indication of a network configuration problem. However,
StorEdge can be configured to prevent this situation.
This functionality is only available at the StorEdge CLI (command line interface).
1. To access the StorEdge CLI, connect to the StorEdge via Telnet, and type “admin”
at the [menu] prompt and enter the administrator password.
2. To disable ICMP requests to change the default gateway, enter “set
default.gateway.redirect no” at the CLI. Press the [Enter] key.
After setting any variables on the StorEdge, i.e. anytime the “set” command is used,
the command "savevars" must be entered at the command line in order for the
settings to persist though future server reboots.
How can I disable RIP routing?
RIP, or Routing Information Protocol, is a method for exchanging routing table
information among routers. As this can generate a large amount of traffic in some
cases, and the information may not be needed by StorEdge, it may be desirable in
some cases to disable RIP on StorEdge.
This functionality is only available at the StorEdge CLI (command line interface).
