MX68 not arping Cisco switch

This is really basic but confusing me. I have an MX68 connected to my cisco 4500 switch for testing. I trunked my ISP subnet all the way to the Cisco switch and connected the mx68 to it. On the mx side, I gave it a public IP on the wan1 port in the ISP subnet, on the switch side, it is an access port in isp vlan. Issue is, I don't see the mx68 MAC added on the switch side neityne is internet available on on the mx68. What am I doing wrong?

 

MX----acess--SW---trunk---Router-----Fortigate-----Internet

Re: MX68 not arping Cisco switch

Can't help you there but I was wondering which firmware is your MX68 running? The minimum firmware version is 14.32 which doesn't even exist in beta.

Kind of a big deal

Re: MX68 not arping Cisco switch

Your best bet for this type of config is to setup the switch port going to the router as access vlan X.  Use a VLAN you don't use for other stuff.  Then setup the port going to the MX as access with that same VLAN you used above.  Then you should be good.

Re: MX68 not arping Cisco switch

If you plug a PC into that same access port with the same IP configuration - can it access the Internet and perform name resolution?

Re: MX68 not arping Cisco switch

UPDATE:

 

I can see the MAC address of the MX now no my Cisco switch. The issue was a stipid one. I have forgotten to add the vlan of the ISP on the Cisco switch. BUT, i still see no internet even when i directly connect a laptop. I did a ping to the gateway from the laptop

Re: MX68 not arping Cisco switch

I resolved the issue. Very simple one and dump stupid. I had not added the access VLAN on the switch itself
