Solaris 10: cannot ping to/from server

  • 772

All,

I have a Solaris 10 server which is not reachable by IP (ie can't ping to/from the server). I believe I have the default route setup correctly. See below:

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.62.100 netmask ffffff00 broadcast 192.168.62.255
ether 0:14:4f:b1:9b:30

# netstat -rn
Routing Table: IPv4
Destination       Gateway           Flags        Ref        Use  Interface

224.0.0.0         192.168.62.100     U           1           0   bge0
default           192.168.62.1       UG          1           0
127.0.0.1         127.0.0.1          UH          1           4   lo0
#

# cat /etc/defaultrouter
192.168.62.1

I have verified layer1 and layer 2 are up on the switchport, and that it's on the correct VLAN. I have also checked the default gateawy (192.168.62.1) is in fact reachable since I can ping it from my PC:

Pinging 192.168.62.1 with 32 bytes of data:

Reply from 192.168.62.1: bytes=32 time=3ms TTL=254
Reply from 192.168.62.1: bytes=32 time=6ms TTL=254

I'm at a loss as to what is wrong. I would highly appreciated your assistance.

Thank you very much.

UPDATE1:

Don't see ARP entry for default gateway:

# arp -a
Net to Media Table: IPv4
Device   IP Address               Mask      Flags   Phys Addr
------ -------------------- --------------- ----- ---------------
bge0   192.168.77.1         255.255.255.255       00:17:59:01:55:50
bge0   pgw1                 255.255.255.255 SP    00:14:4f:b1:9b:30
bge0   192.168.62.53        255.255.255.255       00:1b:53:36:f5:30

UPDATE2:

I added a static arp entry for the default gateway but this did not help. Please suggest the next step.

UPDATE3:

I moved the server to a different switchport and that resolved the problem. Thanks guys for your helpful suggestions. Peace.

    I have checked an S10 system I have to hand and it looks exactly like yours. Can you try connecting something else to the same switch port and cable to verify them? Is there a second NIC on the system ? 

    # ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
