A Technical Information

After I connect to Local Management I see a blank screen. Why?

Make sure you are using a null modem cable (included).

Check the settings in your terminal program. They should be set to 9600 baud, 8 data bits, No parity, 1 stop bit, and No flow control.

Try pressing c+ R to force the screen to refresh.

I keep getting an intermittent loss of link. (or data is not being transmitted) Why?

You may be using the wrong grade of cable. The wrong cable can cause erratic performance and you may eventually lose the connection between the port and the attached device.

Check the duplex setting for the device connected to the port. You may have to use the Local Management or Web Device Manager to force the port to half or full duplex.

A cable segment somewhere in your collision domain may be too long. Make sure none of your UTP cabling is longer than 100 meters.

Check the Ethernet cable pairs. The TX pairs (pins 1 and 2) and the RX pairs (pins 3 and 6) should be twisted pairs. See diagram in page 10.

I created a tag-based VLAN, and I have tag-capable LAN adapters in my PCs, but I can still communicate with devices outside the VLAN. Why?

Check to make sure that you have assigned a VID to the PC. If you don’t assign a VID to the NIC in the PC it will behave as an untagged device. The default VID for untagged devices=1 so all untagged PCs will be a memberoftheDEFAULT_VLAN.

Locating MIB files

If you use a MIB browser, you can configure or view statistics for the switch. You can find these switch MIB files at the Intel Customer Support Web site at http://support.intel.com/support/express/switches.

intel.mib

int_pbrd.mib

int_gen.mib

int_qprd.mib

int_s460.mib

 

 

When compiling the MIBs into an SNMP-compliant management application, compile the intel.mib first then compile the int_gen.mib, int_s460.mib, int_pbrd.mib, and int_qprb.mib files.
