I've just acquired a new network and having some trouble managing some servers/switches across the interconnect and looking for some help.
I have a 5412zl 10.215.x.x/16 Most of the connections on this switch are on vlan1. B9 is the port which is connected to a Cisco 2821 Router. The port on that end is GE0/1. The port on the cisco side is not a trunk but configure with an ip of 10.215.1.30/24
Its part of a some ip access group. The network that i now sit on is a 172.x.x.x/24 (behind cisco router, about 3 hops to that main 2821)
We current have a system on my side that talks to a server on the 10.215. that has no issues. I'm trying to access some switches on the 10.215. and have had no luck reaching them.
Here is the access list that i found that port is configured to use:
permit ip 10.215.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 126.96.36.199 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 188.8.131.52 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.215.0.0 0.0.255.255 192.168.20.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.20.0 0.0.0.255
I would think the first permit would allow me to get through to the 10.215 side but maybe i need to set something up on the hp size to let it know how to get back? I'm very new to this stuff.
Network A - Cisco - mainly all 172 network..but we have others. that side handles 10.10., 192.168. Network in question. On this router only 4 network interfaces i believe. one interface has as ip applied to it. 10.215.1.30/24. i was told that everything from the 10.215.x.x/16 side goes through that connection to see stuff over on 172.x.x.x side. Everything from an application and user perspective is working and has been working for about 5 years. Now that i'm managing Network A and B...I cannot manage switches on network B from network A.
Network B - Hp - Only 10.215.x.x. All the devices on this network have a gateway of 10.215.1.1 (checkpoint firewall). the port of the 5412zl that connects to the cisco there's no ip assignment, just a regular switch port.
Every gateway on the Network B side and including the port configured on the Cisco 2821 172.18.0.2 switch is the checkpoint firewall. 10.215.1.1
Everything (95%) on the Network B is on the default Vlan, i know this is bad and i'm going to be changing that.
From Network A i can see computers and servers on the 10.215. /16 side. Normally they're 10.215.2.x-10.215.99.x. I cannot ping, ssh, or telnet into anything 10.215.1.1 /16
All switches on network B are configured with a gateway of the firewall.10.215.1.1
1. I need to be able to manage Network B's switches from a Network A admin machine.
2. I have a monitoring server on the network B side that needs to monitor network A's devices.
3. Why is the port on the Cisco side setup with a /24 when my network A is a /16? ( more like a question)
1. Am i missing a route in there?
2. Is there an ACL that is blocking that traffic?
I'm attempting to attach a diagram layout of my situation along with the running-config files from both switches.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci- dessous
si je le lier avec mon pc portable sur l un de ses ports directement ça marche toute est bien ( la connexion internet + m...
Attached policy provides CLI access to the Cisco 4G router over text messaging. Two files are in the attached .tar file:
