MSA1510i + Cisco 3560G switch + VLANs problem

Hi All,

We just bought an MSA1510i and are trying to connect this to a Cisco 3560G switch, but we're having problems with VLAN configuration.

We have two VLANs in our test scenario, VLAN 1 (main network) and VLAN 121 for the SAN.

We're trying a test configuration on the MSA1510i like so:

CLI> show management

Management Status: Enabled
Management Port: MA0
MAC Address: 00:12:79:68:d6:f4
802.1Q VLAN ID: 1
DHCP Enabled: No
IP Address: 10.100.1.60
Network Mask: 255.255.255.0
Default Gateway: 10.100.1.1


CLI> show ip
Port IP Address Subnet Mask VLAN ID
---- --------------- --------------- --------
SA0 10.100.121.60 255.255.255.0 121
SA1 10.100.121.61 255.255.255.0 121


And we have the following configured on the switch (SA0/MA0 is on port 33, SA1 is on port 34):


interface GigabitEthernet0/33
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,121
switchport mode trunk

interface GigabitEthernet0/34
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 121
switchport mode trunk


We get good connectivity on 10.100.121.61 (SA1), no response at all from 10.100.1.60 (MA0) and 90% packet loss from 10.100.1.61 (SA0). This has the network guy blaming the MSA1510i!

I realise this could be an issue with the Cisco switch, but we're not sure because we already have a trunk port configured in exactly the same way for a server with three VLANs and three virtual NICs configured with the HP Network Configuration Utility.

Any help someone could give would be greatly appreciated! What are we missing??

Thanks,

- Simon

Re: MSA1510i + Cisco 3560G switch + VLANs problem

You use two adresses within the same ip-subnet.
SA0 10.100.121.60
SA1 10.100.121.61
I don't think this is what you want to do.
Effectively the box will listen to both adresses but send with only one (i think the lowest max adress).
