Hello! We have a LAN including a lot of L3 Cisco switches, each of them is gateway for CCTV cameras. All traffic from cameras continuously writing to VMS server. Network is quite huge, it might be about 1000 cameras connected to 1 L3 switch. The...
Hello. There is an network, using 4 Cisco ASR as layer 3 gateway for ring of layer 2 Cisco switches. Topology looks like square, which angles is ASR-s, and sides is connected one by one by chain topology, which makes an enclosed loop of a layer 2. Lo...
Hello everyone! There is a huge local network based on server with applications and users of different remote branches, what use these. Rest of servers protected by firewall Palo Alto, and have gateway on it. PA connected to the core switch. But ther...
Greeting everyone! There is a little problem with configuring tacacs server on ws-2950-24 model switch. The rest switches we have are 2960 series, also 3xxx series and others, more modern versions. We always configured tacacs server this way:tacacs-s...
Hello everyone. There is a couple questions about OSPF topology. As it known, ABR routers - routers which connect its area to zero area. For example, 0,1,2 areas, and there is only 1 ABR router on each area, then there is only 2 ABR could bi in this ...
Yes, the issue with the main VMS must be resolved in any case. Even though it occurs rarely, those few incidents were enough for the clients of the other VMS servers to lose confidence. As a result, they now want to receive traffic directly from the ...
Right now, in our network, the main VMS is already acting as a traffic distributor for the other VMS servers. The cameras send unicast traffic to it, and it then forwards it further to the rest.The problem is that sometimes the main VMS hangs, and wh...
We had a call with the VMS side yesterday. They said multicast is not really suitable for recording since it's UDP. You can get packet loss, which means gaps in the archive, and that's a big issue for us.For us, archive reliability is more important ...
From a purely logical point of view, this seems like the best option. But right now we’re trying to find a practical solution, and instead it feels like we’re going even deeper into theory.Also, when we asked about this approach during consultations ...
You are right — it is possible that multicast may turn out to be unsuitable for our network. For example, the current VMS may only operate over unicast, such as recording archives exclusively via unicast. Some legacy 8-port switches, to which the cam...
