Network setup - identical except one is reachable and one i'snt.

Hi

 

I have an RP8420 with a NIC configured at:

 

lan6: flags=1843<UP,BROADCAST,RUNNING,MULTICAST,CKO>
        inet 172.21.99.2 netmask ffffff00 broadcast 172.21.99.255

Routing tables
Destination           Gateway            Flags Refs Interface  Pmtu

default               10.82.1.254        UG    0    lan7       1500

My rp7420 says:

 

lan3: flags=1843<UP,BROADCAST,RUNNING,MULTICAST,CKO>
        inet 172.21.99.1 netmask ffffff00 broadcast 172.21.99.255

Destination           Gateway            Flags Refs Interface  Pmtu

10.99.53.1            10.99.53.1         UH    0    lan0      32808
172.21.99.1           172.21.99.1        UH    0    lan3      32808
10.99.53.0            10.99.53.1         U     2    lan0       1500
172.21.99.0           172.21.99.1        U     2    lan3       1500
127.0.0.0             127.0.0.1          U     0    lo0       32808
default               10.99.53.254       UG    0    lan0       1500

The 8420 is pingable, my 7420 isn't.

 

Green lights show on both servers.  Also they are flashing orange.  Our switch can see the MAC of the 8420 172.21.99.2 but not the MAC for th e7420 172.21.99.1, but show physical connections in.

 

I'm stuck.

 

Regards

Re: Network setup - identical except one is reachable and one i'snt.

What does:

 

# lanadmin -x 3

# netstat -in

 

return on the rp7420?  Is it actually connected?

 

Is the switch set up for the appropriate vlan for that server?

Morning Patrick

 

The switch is configured correctly as the server on the address one up from this pings fine.  These are both on the same vLAN.

 

root@server at / =>lanadmin -x 3
Speed = 1000 Full-Duplex.
Autonegotiation = On.

root@server at / =>netstat -in

As comparison, here is the same from the good server on the .2 address.

 

root@server.2 at /home/root =>lanadmin -x 6
Speed = 1000 Full-Duplex.
Autonegotiation = On.

root@server.2 at /home/root =>netstat -in
