How to connect devices in a different IP block to my ICX 7450 stack?

Hi everyone, I have 6 ICX 7450 switches running in stack mode and currently in switching (L2/SPS) mode. My existing network is on the 10.10.10.x subnet. I need to add 4 new devices with IP addresses in the 169.254.1.x subnet. These devices cannot have their IPs changed, but they need to communicate with a server at 10.10.10.1. Since the switches are currently in L2 mode, I cannot create VLAN interfaces (VEs), so inter-VLAN routing is not possible. My question: Do I need to switch the stack to L3 mode (SPR) to make these two IP blocks communicate? Or is there a way to do this while staying in L2 mode? Any advice or recommendations would be appreciated. Thank you!

ICX 7450 won't pass traffic to a Mellanox SN3420M

Installing a pair of newMellanox SN3420M switchesCross connecting them to an existing stack of ICX 7450 using an LACP etherchannel of 2x 10gb fiber linksEtherchannel comes up, but won't pass any traffic.Ruckus T1 + nvidia support confirm the configuration is correct, VLAN settings are the same on both sides, LAG group comes up active/active, packets are flowing but can't get any VLAN traffic over the link.Tried a single non-etherchannel link, same issue.Anyone run into this before?Can anyone confirm if there's a firmware upgrade to fix this before we call another weekend outage?

ICX7150-24P No HTTP or HTTPS access on 9.0 or 10.0

HTTP and HTTPS both work perfectly on 08.0.95s. I tried on both 09.0.10k and 10.0.10g_cd3 and can't get the web interface working at all."crypto-ssl certificate generate" doesn't exist at all in the cli after upgrading.ICX7150-24P Router(config)#cry crypto Crypto configuration ICX7150-24P Router(config)#crypto key key configuration openssl Modify openssl settingsI tried HTTP and HTTPS:ICX7150-24P Router(config)#show web HTTP server status: Enabled HTTPS server status: Enabled No web connection.nmap:Starting Nmap 7.98 ( https://nmap.org ) at 2025-11-10 11:12 -0600 Nmap scan report for 192.168.1.20 Host is up (0.0043s latency).

R550 duplicating packets

I am using the R550 as a local access point with no connection to the Internet. I have written a Mac app that streams SDP messages and RTP/UDP packets over multicast via WiFi using the R550. I have verified the Mac only sends one packet at a time, and that the R550 is receiving and sending those packets along to another app I wrote running on my iPhone. But the R550 is duplicating packets, sending two packets for every packet it receives (confirmed by collecting and examining packet traces from the R550 itself - two packets being sent at the same timestamp). I have updated the R550 firmware to the latest version, and configured my R550 AP as follows:disabled SmartMedia QoSdisabled directed multicastset the qos directed threshold to 0disabled qos mirroringusing the 5GHz radio onlyset BSS minrate to 12enabled OFDM onlyset DTIM to 1Even after all this, the R550 continues to duplicate packets. No duplication when I remove the R550 from the signal path entirely and hard-wire my Mac and iPhone together via ethernet cabling to the same network switch.These are media apps that don’t tolerate such duplication. How do I make it stop?All considered thoughts and suggestions appreciated.Cheers, Martin

R760 resetting / possible thermal issue

I have two R760 APs powered by Trendnet 10G PoE++ injectors, which provide the correct amount of power.The access points start at room temperature but gradually heat up and then reboot after about 40–60 minutes of uptime, even with minimal to no network activity. Something is clearly wrong with the devices, and I’m assuming it may be a firmware issue. I’m currently running 118.2.0.0.875, which I was only able to upgrade to using the CLI. After the first reboot, the device continues rebooting every 10–15 minutes. This may be some sort of thermal protection behavior, but I’m not sure.These APs are not being used for WAN—only for a private network to access audio-visual devices. No other users are on the network besides me.I am using these as standalone devices. One is set to xxx.xx.x.250 and the other to xxx.xx.x.251. They work properly with except of the reboot cycling.Please help me resolve this issue.
