I migrated a stack of 9300's in my lab and it was fairly simple, but it takes a long time for them to come up in a usable state to configure the management vlan and IP on the management port.  The switches rebooted multiple times over a couple of hours before they were finally stable. Going to be a pretty big maintenance window to upgrade to a supported image and then have several hours of downtime before you can even start configuring them.     A few other issues to note.  There's no port profiles for the C9300's so you have to configure the ports currently.  The C9300's list a bunch of extra switchports that don't exist.  IE I have C9300UN's so it has the 48 ports, 2 stacking ports, and the NM-8X.  But the switchports configuration lists 48 ports, 2 Stack, 2 C3850-NM2-40G's, 4 C3850-NM4-10G's, 8 C3850-NM8-10G's, 2 C9300-NM-2Q's, 8 C9300-NM-8X's, 2 2x40G, 4 4x10G, and 8 8x10G ports. ...

We disabled it as well because of Petitpotam.  I guess that makes sense why my local auth won't work.  A bit disconcerting that a security product only supports an insecure legacy protocol. ... View more

Everytime I've had this issue the carrier has had to clear the arp cache on their modem.  Rebooting the mx breaks it again. ... View more

Alex,   I agree, it's not going to be cost effective to rip and replace especially when the new models with built in cellular are nearly twice the price as those without.   ... View more

I was originally really excited about the built-in LTE, but it would be nice if it was available on the non-wifi model too since I run separate AP's anyways and it really shouldn't be nearly double the cost.   The speed increase is always welcome, but out here in the rural area's where I have them deployed I'm not anywhere close to hitting the limits on my MX64/65's.   ...

No, but we have used other Digi products for serial communications for the past 20 years.  Always been rock solid. ... View more

Alex,   We've had similar issues with the USB Modems from Verizon.  More often than not they're not working when we need them so they're of very little use in an outage.  I've looked at Cradlepoint as well, but as you mentioned they are too pricey for me to justify using one as a modem at each site. I did find these modems from Digi that might be worth a shot.     WR11-M600-DE1-XB  ...

Just curios if this has been fixed for anyone else or not.  I'm running MX14.19 and it seems to be working now at all my sites.  I'm assuming COX fixed something as I haven't updated for a while and it just started working at some point recently.     ... View more

Has anyone heard any updates on this issue?   I was hoping MX 13.27 would fix it, however it did not. Corrected an issue that resulted in static IP addresses assigned to the MX WAN interfaces incorrectly failing back to IP addresses acquired via DHCP   ... View more

What version of firmware are you on?  I just upgraded to the latest 13.24 and am now seeing the same issue with my sites on Cox.  I did not see this issue previously when on version 12.24.     I assumed this issue was fixed in this update but apparently not. 13.21 Resolved a case where MX appliances would not resume using their assigned static WAN IP address after a failover to DHCP occurred due to the absence of connectivity on the assigned static IP address ...
