Cisco 2960 switches pull in cool air from the sides and exhaust to the rear. Depth-wise they are 1/3 to 1/2 rack-depth (depending on exact model switch and rack). This leaves you very few options. If you mount them unmodified backside of the rack just about the entire switch is in the hot zone. That will only be OK if you have cold airflow running on the ...

If it is OK for you to change the default gateway of your clients to fail-over, you just need to configure 192.168.10.236/24 on your VDSL router's LAN interface and connect it to your switch (note that if your are using DHCP, you should probably also disable the DHCP server in the VDSL router so you don't have two DHCP servers in the network).

I would assume that the problem is in your routing table. E.g., ip route 10.1.1.0 255.255.255.0 FastEthernet0/0 ip route 10.1.1.0 255.255.255.0 192.168.1.0 According to these commands, all IP packets to 10.1.1.0 network will be redirected either to FastEthernet0/0 (which means back to 192.168.1.111) or to 192.168.1.0 (which probably means nowhere, since ...

Im guessing the AT&T has a LAN side IP address, in which case you need to create a default route on the cisco router that sends all traffic with a destination of unknown networks to the lan side interface on the AT&T box. ip route 0.0.0.0 0.0.0.0 IPOFAT&TLANINTERFACE This means the next hop of any 'unknown network' traffic such as traffic to ...

Without knowing if you have other switches and which switch is the root bridge I can't give you a specific answer. with spanning-tree vlan 2-400 priority 8192 you lower the priority for Sw1 for vlan 2-400 which means it will become the root bridge unless there exists a switch with lower priority (lowest priority becomes root bridge). So if Sw1 was not ...

Translate a whole network range is possible by using static NAT (aka Net Static). Anyway the problem here is that old network is a /8, while the new can be 172.16.0.0/12 at most (you forgot to specify this). So, unless you want to specify the translation of each IP needed, a good idea could be to select a subnet of 10.0.0.0/8 with the same size of your new ...

One-to-One Nat is needed... so, you'll need to make sure that you create: ip nat inside source static 172.16.0.30 2.2.1.2 You'll also want to remove your PAT translation ip nat inside source static tcp 172.16.0.30 25 2.2.1.2 25 extendable ip nat inside source static tcp 172.16.0.30 80 2.2.1.2 80 extendable ip nat inside source static tcp 172.16.0.30 443 ...

I have been using this perl script for about a year now. it's an evolution of several snippets of perl scripts i have found on various forums plus a bit of trial and error but it works well. You will need to install the module Time::HiRes for the usleep, but i found that it helps with execution of commands on remote switches and routers where the response ...

First, I know this is old'ish but want to clear the record for posterity. You are right to be VERY concerned however neither Cisco nor any other vender seems that interested in fixing the issues you identified. When using RADIUS (or TACACS+) for authentication your password is encrypted using the shared key you configured. Note that the shared key is ...

EIGRP falls under the category of distance vector routing protocols which means that it "routes by rumor". So the topology table does only contain information which it has received from its neighbors which is not necessarily all information about the network since distance vector protocols only tell their neighbors about the best routes as opposed to link ...
