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

10.82.1.66 10.82.1.66 UH 0 lan7 32808
172.21.99.2 172.21.99.2 UH 0 lan6 32808

127.0.0.0 127.0.0.1 U 0 lo0 32808
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

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
Tariq

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?

Re: Network setup - identical except one is reachable and one i'snt.
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
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lo0 32808 127.0.0.0 127.0.0.1 18259 0 18262 0 0
lan3 1500 172.21.99.0 172.21.99.1 56 0 78 0 0
lan0 1500 10.99.53.0 10.99.53.1 626960 0 256602 0 0

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
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
