Hey all, I'm having toubles with multicast (I think) between a Cisco SG350 and a network of Netgear 4250 AVline switches. The netgear switches are setup in a star config with the Cisco joining the "core" netgear. All seems to work however I'm having issues with a lighting node that requires multicast. The node is doing weird things so I am try to force send a specific multicast address to it. I believe everything should be configured properly. Some switches it seems to work but others not (configured the same I believe just a different number of ports). I'm using MAC filtering under traffic control for this. The second issue I'm having (could be related) is I can't find how to completely disable the IGMP querier on the netgear switches for a specific VLAN. I am using the Cisco as the Querier but the netgears keep electing themselves even with election participte disabled on all. Most of the networking I know is self taught so could easily be wrong. Any suggestions would be much appreciated. Thanks16Views0likes1CommentM4250 configuration needed to allow DHCP passthrough
Hello, I am currently working on an AV system where I have a Crestron CEN-SWPOE-5AC (5-port unmanaged Gigabit Ethernet switch), and I am planning to replace it with a NETGEAR AV Line M4250-26G4F. My goal is for the NETGEAR switch to behave the same as the Crestron—essentially plug-and-play, operating like an unmanaged switch with no special configuration. The main switch in the building is a Cisco switch that acts as the DHCP server. With the Crestron switch, my devices receive valid IP addresses in the range of 10.103.19.x (for example, 10.103.19.7 and 10.103.19.23). However, when I connect the NETGEAR switch, the devices are instead receiving 169.254.x.x addresses. What I am trying to achieve is for the NETGEAR switch to pass DHCP correctly so that my devices receive the same type of IP addresses as they do when connected through the Crestron switch. Could you please advise what configuration is required on the NETGEAR switch to make it behave like an unmanaged switch and allow proper DHCP assignment from the main Cisco switch? Thank you in advance for your help.80Views0likes1CommentGC108PP managed switch: how to change management VLAN?
System -> Management -> IP Configuration has a text box for "Management VLAN ID". I have VLANs configured on this switch. When I try to set the value to anything other than the default of "1", I get a popup stating: "Error! Management access will be lost on MGMT VLAN configuration." No problem I figure, so I click OK. Nothing changes - the management VLAN is still 1. The online help and the owner's manual state that it should be possible to change the management VLAN. I'm running the latest Firmware Version V1.0.8.10. Any ideas?Solved184Views0likes4CommentsM4300 SNMP zabbix problem
Dear All! I tried to start to monitor my netgear switches, and on the server i choosed the built in netgate template. Works fine expected two things, the psu and the fan recognize is false, found a few threads about this but no solution. At mapping i see this: The switch default state is two, so thats noot good, and if i try to snmpwalk th oid i get only 1 and 2 for value if im doing it good. The fan state is fan 0: 1.3.6.1.4.1.4526.10.43.1.6.1.3.1.0 and gets 2 what is fault in the value, but cannot figure out what is the correct value. Now to solve the problem in the mapping i switch operational and failed value, and in the macro set the fault to 1, now its reports okay but im not sure its 100% will work when i have a fan error. PSU the problem i have is the psu0 has problem and i dont know why.460Views0likes5CommentsM4300 24x24F Stack member failure
Hello We are having situation where 02 member of two member stack is crashing for unknown reason. We had this crash multiple times on various firmware. We do not run multicast and traffic is really low. Topology is star with redundant links to access layer switches(aruba), we use SPF+ 10G 12.0.17.16 Symptoms, high CPU reported, no obvious reason for it(eg extra traffic). When logged into GUI, CLI to investigate. CPU would go back to normal and we were unable to find out what is causing it. If stack/02 member was not rebooted at this time it would eventually crash in a way where it kept interfaces up, it would eventually fully reboot and join stack. 12.0.19.12 Same as 12.0.17.16 12.0.19.19 No spike in CPU usage. We did get some logs that look useful(attached). Crash happened out of hours with nobody in the office so traffic/usage was real low. Both members of stack were rebooted, but this did not help so right now we run on 01 only. I'll go to remote office to plug console into 02 to see if I can get anything useful. Any idea what could be causing this?110Views0likes2CommentsVlan Combine when Partition Walls controlled QSC
Looking for info/ help. We are using a M4250-26G4F-POE+ with a QSC core to Combine 2/3 meeting room together. We are using a Huddly Crew Cameras (poe) . I'm looking to Combine 3 Different Vlans together to combine all the cameras Is there a Easy way or Do I need to use command line prompts to allow / deny vlan controlling?334Views0likes5CommentsMosaic on decoded IP Stream
Hello guys, I have a network remote comprising of switch netgear gs724T. On One site two different stream are present on the switch with different Vlan and Multicast address Site A 1. Vlan 111 - First IP Stream with a Multicast Address are pooled on port 3 4 & 5 to be connected on decoder and the stream are fine 2. Vlan 112 - Second IP stream with a multicast address is originated from an ip decoder and connected to port 11 and 12 where to be decoded on site b On Site B 1. the Vlan 112 is beind decoded and monitored where the video is MOSAIC. Note From site a to site b microwave link is used with a capacity 1 gbps and all config is ok IGMP was configured globally and for each VLAN. the issue of mosaic persists kindly advise for a solution Thanks309Views0likes13CommentsM4350 switch doesn't fallback to guest network
Hi, I trying to setup 802.1x (EAP-TLS) with a fallback guest VLAN. 802.1x works correctly for devices that have the certificate, but devices that don't send EAP packages don't get put in the guest VLAN (666). They just get stuck in with an 169.254.X.X address. Below is the relevant config: vlan database vlan 101-102,666 vlan name 101 "Office" vlan name 102 "Voice" vlan name 666 "Guest" set igmp-plus 101 set igmp-plus 102 set igmp-plus 666 set mld-plus 101 set mld-plus 102 set mld-plus 666 vlan routing 1 1 exit ip http port 49151 configure stack member 1 9 member 2 7 exit switch 1 priority 14 switch 2 priority 15 username "admin" password xxx encryption-type sha512 level 15 encrypted authentication enable dot1x software version 1 aaa authentication dot1x default radius authorization network radius radius accounting mode radius server host auth "192.168.1.252" name "nas001" radius server key auth "192.168.1.252" encrypted xxxx radius server primary "192.168.1.252" radius server host acct "192.168.1.252" name "nas001" radius server key acct "192.168.1.252" encrypted xxxx line console serial timeout 60 exit interface 1/0/1 authentication periodic authentication timer reauthenticate 60 authentication event fail action authorize vlan 666 authentication event no-response action authorize vlan 666 dot1x timeout quiet-period 3 dot1x timeout tx-period 5 spanning-tree edgeport switchport mode access switchport access vlan 666 exit Any idea's what I'm doing wrong?
