200
|
Unspecified hardware problem.
|
Reseat the network interface card.
If the problem persists, contact Network Appliance support.
|
201
|
Link not detected.
|
Complete the following steps until you detect a link:
- Ensure that there is a cable
connecting the network
interface card to the network.
- Check the cable.
- Check the interface card and
corresponding switch port
setting for a speed mismatch.
- Check for a switch or hub port
problem.
- Reseat the network interface
card.
- If the problem persists, contact
Network Appliance support.
|
202
|
A link on an Alteon Gigabit adapter is not detected because of an autonegotiation mismatch.
|
Change the interface configuration or peer switch port configuration so that the settings match.
|
203
|
No link is detected because of a speed mismatch.
|
Change the interface configuration or peer switch port configuration to match the speed.
|
204
|
The interface not configured up.
|
Configure the interface up.
|
205
|
Duplex mismatch.
|
Change the interface or peer switch port duplex setting so they match.
|
206
|
Link capacity problem.
|
Upgrade to a faster interface.
|
207
|
The interface not transmitting or receiving.
|
Complete the following steps:
- Pull out the network cable from
the network interface card.
- Reinsert the cable.
- Change the media type using
the ifconfig command, wait
five seconds, then restore the
media type to the previous
setting.
- If the problem persists, contact
Network Appliance support.
|
208
|
Excessive I/O errors.
|
Complete the following steps:
- Reseat the interface card.
- Check the cables.
- If the problem persists, contact
Network Appliance support.
|
209
|
Excessive unsupported protocol packets are sent to the filer.
|
The problem is not with your filer.
Contact your network administrator to resolve the problem.
|
301
|
The IP address and netmask are inconsistent with the assigned broadcast address.
|
Change the configuration using the ifconfig command.
|
302
|
The broadcast address reaches a larger set of hosts than the standard broadcast computed from the IP address and netmask.
|
If this behavior is erroneous, change the configuration.
|
303
|
Excessive IP reassembly errors.
|
Switch from NFS over UDP to NFS over TCP.
|
401
|
The TCP window advertised by the client is too small.
|
The problem is not with your filer.
Reconfigure the client.
|
402
|
Excessive packet loss on the sending side.
|
The problem is not with your filer.
Examine the network and client for congestion.
|
403
|
Excessive packet loss on the receiving side.
|
The problem is not with your filer.
Examine the network and client for congestion.
|
404
|
Poor average TCP packet size on the receiving side because the network, client, or both are not enabled to support jumbo frames.
|
The problem is not with your filer.
Enable support for jumbo frames in network devices and the client.
|
405
|
Poor average TCP packet size on the receiving side because of a problem with the network, client, or both.
|
The problem is not with your filer.
Examine the network and client for configured MTUs.
|
406
|
Poor average TCP packet size on the receiving side because of a client application problem.
|
The problem is not with your filer.
Examine the client application data transmission strategy.
|
407
|
Excessive TCP listen socket drops because the system is overloaded or under security attack.
|
Contact your network administrator to resolve the problem.
|
408
|
Excessive filtered TCP port drops because the system is under security attack.
|
Check your network.
Contact your network administrator to resolve the problem.

|
Excessive embryonic TCP connection drops because the system is under security attack or because a client has a bug.
|
Contact your network administrator to resolve the problem.
A packet trace might assist in locating the problem.
|
410
|
Excessive TCP checksum errors because of a client or a network that loses packets when loaded.
|
The problem is not with your filer.
- Check your client system for bugs.
- Your network might be overloaded.
- Contact your network administrator to resolve the problem.
|
411
|
Bad packets because of a client. Your system might be under a security attack.
|
The problem is not with your filer.
