M4250 Switches Power Outages and UPSs
Hello, I am working in a new theatre that was setup in some interesting ways. We are currently working our way back through the system and altering things to follow better practices. As it is a new building we are still dealing with power shutdowns as new equipment is installed/changed. Everytime there is an outage it feels like something new breaks. We have UPSs that our "critical" devices are (sometimes) attached to. This includes our network switches. But the batteries can only supply power for ~40 minutes at current load. Our UPSs have an expansion slot that we can add an SNMP network card into. Is it possible for our network switches to monitor for outages and power off nicely? Is there such a thing as shutting down the switches nicely? What is the best practice for shutting down a NetgearAV switch? Another thing that causes outages for us is the fire alarm. We are required by the fire marshal to shutdown our whole system as soon as the fire alarm goes off. So currently everything loses power (except the UPSs which I think goes against the fire code... like I said... interesting setup) and I am trying to find better ways to manage shutting down the PA system but keeping critical equipment online long enough to shut down correctly before powering down entirely. We've had some false alarms from a poorly placed smoke detector in a catering kitchen and I would love to have a system that can shutdown according to code but do so nicely in case it is a false alarm. I've had a bad experience with shutting down the M4250 switches. Early on when we opened we had a switch catch on fire after flipping the power switch to reboot it (following instructions from the installer) I want to prevent having this happen again. I'm just interested in how people manage outages and turning equipment on and off.PC sending NDI to another PC...what QOS ?
We have a PC1 sending video using NDI app to Another PC2(receiver). PC1 is on Port 10, PC2, is on port 20. We assigned Port 10 to Queue 5, but we have no idea if this is even working or if we need to modify more things ? We have a M4300 series switch What should the Global Trust Mode setting be? Trust dot1p or IP-DSCP? Do we modify anything in 802.1p to Queue Mapping 802.1p Priority for such a setting? Do we modify anything in IP DSCP to Queue Mapping ? Lastly how can we verify if the settings are working correctly?Issue configuring VLANS
Hi, I am attaching a M4250 switch to a corporate network and am assigned the IP address rage of 172.30.0.1 to 172.30.254.254. There is a DHCP server that uses the 172.30.0.1 to 172.30.0.254. The rest of the IP addresses are available for me to use as static IPs I would like to have 3 VLANS - control, Crestron NVX, and Dante. When I setup the Crestron NVX using 172.30.30.X with DHCP for 8 of the ports I receive the message "VLAN IP address and Default Router must be in the same subnet." I set the VLAN IP as 172.30.30.1 and the DHCP range to 172.30.30.100 to 120. I tried several different variations but still seem to generate this same error. Why do I keep getting the "VLAN IP address and Default Router must be in the same subnet." error message? Any advice on what IP scheme to use to work with the 172.30.0.x network? Thanks, DavidM4300/M4250 - Keeping multicast on switch
I have several M4300 / M4250 switches set up for a customer with various Crestron NVX implementations, all of which is working well. We have a very basic connection to the customer's existing network by simply connecting a standard gigabit port on the M4300/4250 (port 48) to one of their switches, used only for remote access and diagnostics. We are not directly trunked to their switches or stacks, in effect we appear as a simple unmanaged switch to their equipment (BPDU filter, disabling STP on that port - I know, I know, not good things to do, and will ultimately be resolved properly). We want to make sure multicast does not leave our dedicated M4300/4250 switch, and block all multicast traffic from leaving (or entering) port 48. In effect, I want to make sure all multicast is blocked inbound and outbound on that single switch port, but allow other TCP/IP traffic for remote diagnostics, etc. I've tried using the Configure>Multicast -> Block Multicast method in the AV GUI webpage: But I still see multicast traffic entering and leaving the switch on port 48: Does anyone have any suggestion on ensuring that all multicast traffic (even if it's by IP/range) stays on the switch and does not traverse my "uplink" port 48? Thanks JayNetgear M4250 setup with NDI and Dante VLANs plus Internet on both
Hi, I would like to have Dante and NDI available but I would like to keep them seperate as I have experienced Dante issues when NDI is on the same network. Even when using the NDI with Dante Profile provided by Netgear. Can someone advise me how I would: Use a standalone router to provide DHCP for all devices and all VLANs plus provide internet to all VLANs. Configure M4250-10GX2XF to connect to Router on Port 1, have Ports 2 - 6 as a NDI Router and 7 - 10 as Dante leaving 11 which has a 10G RG45 in it to connect to a computer on the NDI VLAN and Port 11 which has a 1G Fibre SFP to Autotrunk to a M4250-9G1F which I would like to use with a mixture of NDI and Dante VLANs as well. Firstly is this possible to use the standalone router to give IP addresses to all the devices connected to both switches and do I need to leave 1 port on both switches on the default management VLAN to manage the setup?
