CSS326-24G-2S+ management

Thu Jul 06, 2017 9:00 am

Hello,

we have just got our hand on a CSS326-24G-2S+ and trunk and access ports work as they should and we were able to configure them with the old documents from mikortik.
we are stuck on the management IP part.
we need to set the management ip 10.0.0.1/29 on vlan 100 so that we can access the switch remotely.
any help on it would be much appreciated.

Thank you
Niamul

i found this while browsing the forum

"NOTE: The management IP for the switch is handled a bit differently. You must create a Vlan1 with ID=1 on the physical interface that will trunk to the switch. Then bind your management IP to that Vlan1 interface. In the example above, you would bind 192.168.88.2/24 to Vlan1 and then you can access the switch through the trunk port."

Dearest Mikrotik, everybody wants to avoid using vlan1. there is no vlan1 running on our network for that reason, yet i will have to run vlan1 to access the switch? there is no other way?

The IP and VLAN can be set in the "System" tab. However, SwOS doesn't know anything about netmasks and gateways. Communication only works on the same subnet.
The solution I use is to configure source NAT (masquerade) for communication towards the switch on the last router (in my case there is only one router) before the switch. Then the source IP appears to come from the same subnet and the switch's answer will reach the router and be NATted back to you.

the problem here is the vlan 1

this switch will sit far far away from where i'm at and enabling vlan1 on a network is a no no for me.

hence i'm looking for an alternative.

The VLAN1 is not mandatory for accessing SwOS. Perhaps, it was mentioned just as an example in some configuration guide.
Here is configuration to have management IP 10.0.0.1/29 on VLAN100 in SwOS:

Note that VLAN100 should be configured first in SwOS to avoid losing connection to the CSS326.

Dear becs,
thank you for writing back. that is what we had done.
in our case though, we used real ip 123.123.1.2/30, with 123.123.1.1/30 being elsewhere
since there is no way to add a default gateway to the switch, we could try switching the IP's, though i'm not too sure how that would work.
are there any ways to telnet or ssh into the switch instead of using the gui?
we will give it a go and write back.

cheers,

Niamul
