SUN网卡工作状态检测

以前论坛讨论过，这个是从SUNSOLVE粘贴来的 INFODOC ID: 47729

Below are several methods, with examples, to check network link status of ethernet interfaces in Solaris.

-------------

checking messages:

Sep 18 11:51:08 server1 qfe: [ID 349649 kern.notice] NOTICE: SUNW,qfe0: No response from Ethernet network : Link Down - cable problem?

Oct 1 08:37:06 serrver2 unix: SUNW,hme0: 100 Mbps full-duplex Link Up

-------------

checking link status with ndd

# ndd -set /dev/qfe instance 0 (instance set to "0" checks qfe0 status; "1" for qfe1,etc...)
# ndd  /dev/qfe link_status
  1
  ( 1 -up, 0 = down )                        
--------------------

Checking link status for Gigaswift Ethernet(ce) is different from other Ethernet interfaces.  netstat
-k is used:

netstat -k ce0

link_up (1=up,0=down)                                               
-------------

checking with kstat (netstat -k)

# kstat qfe:0::link_up
module: qfe                             instance: 0
name:   qfe0                            class:    net
          link_up                         1

# kstat eri |grep link_up
link_up                         1

# netstat -k qfe0 |grep link_up
  ......  link_up 1                                                
note: kstat link_up was added by Bug 4167319 : Add additional useful driver kstat variables(hme,qfe, gem)

-------------

examining LED states

newer network interface adapters have light indicators.

on "qfe" quad fast ethernet and "ge" Sun Gigabit Ethernet 2.0 adapters:

   LED      Status         Description
--------------------------------------------------------------
LINK     Off            Port not connected or Link partner down
          Green Steady   Link detected & active                                                
on "ce" Gigaswift:
  --------------------------------------------------------------
LINK QUALITY  Purple   Gigabit link quality good
  PHY 1000X    Green     Link 1Gbit/s up
  PHY 100X     Green     Link 100Mbit/s up
  PHY 10X      Green     Link 10Mbit/s up                                                
-------------

checking with SNMP ( requires snmp Software)
./snmpwalk netlab11 public interfaces.ifTable

...
interfaces.ifTable.ifEntry.ifDescr.1 = lo0
interfaces.ifTable.ifEntry.ifDescr.2 = ce3
interfaces.ifTable.ifEntry.ifDescr.3 = hme0
interfaces.ifTable.ifEntry.ifDescr.4 = qfe0
...
interfaces.ifTable.ifEntry.ifOperStatus.1 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.2 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.3 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.4 = down(2)

-------------

examine Running flag in S9 gigaswift

ce3: flags=1000803<UP,BROADCAST,MULTICAST,IPv4>;
                                
ce3: flags=1000803<UP,BROADCAST,RUNNING,MULTICAST,IPv4>;
                                 ^^^^^^^

  Implemented as part of Solaris 9.
  IP will clear the RUNNING flag if the link is down, and
  set it again when the link is up.

  Bug/RFE ref:  1208229 link status should be reflected by the RUNNING flag, not the
             UP flag                                                
------------------------

mpathd notices

If using Solaris 8 IPMP (IP Multipathing ) mpathd will detect NIC failures and post notices.

  NIC failure detected on qfe0
  in.mpathd has detected that NIC qfe0 is repaired and operational
  Successfully failed back to NIC qfe0 to NIC qfe1
  in.mpathd has restored network traffic back to NIC qfe0, which is
  now repaired and operational.

好，但是要记住以root去执行上面的命令哟！
