I search since Days for a working configuration for a layer2 connection from another extreme switch to this switch. What I connected Physically on my Summit x440-G2-24p:

  • the ethernet(lan) cable from the other switch(Uplink)
  • and a ethernet(lan) cable to my laptop

Actual behaivior:

  • i can't ping outside
  • DHCP Server on 10.1.1.1/10.1.2.1 can't reach from the Summit

Desired behavior:

What I will is that any port of 24 ports uses layer2 one of this serves as WAN(Uplink), also if i will connect another pc it should get an IP address from my DHCP Server.

How looks my config:

  • Please provide the full configuration of your switch, you're not showing any DHCP configuration. And please don't sanitize with #'s, I doubt you configured the same IP address on two VLANs.

  • Running where? You really need to provide a full configuration and a description of your network if you want someone to be able to help you. Also, what do you mean by 'doesn't get an IP address'?

  • No, don't post configurations on external sites. Please keep all information here, so this question and possibly its answers remains useful after the paste has been removed.

configure iproute add default 10.1.4.254

Is 10.1.4.254 is the other switch or a router? if it is the other extreme check if ip routing is enabled for necessary vlans on the other extreme "enable ipforwarding vlan ..." and make sure DHCP servers also have a route for 10.1.4.0/24 network.

  • Yes, it is an other extreme switch, and ip routing is enabled
