Hi Guys,
I currently have two cisco switches (3750) and would like to add a 3rd to the stack, will doing this require downtime of the other two or switches?
We have two core 4506 switches, these feed a number of 3750’s
Stack1 : 3 3750’s connected with custom Cisco cable
Stack2 : 2 3750’s connected with custom Cisco cable
Stack3 – a single 3750 on its own (at present)
We have 8 internal VLANs : 172.33.1.0, .2.0, .3.0 etc
What we want to do is add...
I have remote access to a switch and I need to find out the software image whether it is enhanced or standard. The model is a 3750 but I need to find out exactly which one:
WS-C3750G-24T-S
WS-C3750G-24T-E
WS-C3750G-24TS-S
WS-C3750G-24TS-E
Thanks
Yes the last hop IP address (our Public carriers address) is appearing twice. I thought it may be a routing loop. Is there anything else I can do to troubleshoot as I dont have access to the router?
Thanks!!
If you tracert to one of our external IPs – you get a double hit or duplicate on the last hop. Does anyone know why this might be happening? EIGRP is running on the routers!
Here is my scenario; I have a DSL connection coming in from my ISP… IP address 217.x.x.3. My internal network has an internal address of 192.168.1.0/24, my exchange server is on this subnet and smtp traffic is being routed through our current firewall/router. I have just been given a Cisco 2600...
Thanks so much for your reply. One more question... Since I only have one IP I will have to create NAT mapping for incoming traffic. Is the following command correct and would it apply??
static (inside,outside) tcp xxx.xxx.xx.1 smtp 10.10.0.2 smtp netmask 255.255.255.255 0 0
Thanks
Hey thanks for the reply!
I should of been more clear in my statement. Our ISP does host all our email and pushes the traffic directly to our exchange server after it has been scanned for spam and viruses. But my main question is what acl will I use to allow smtp from those servers...
Hello,
I have one external public IP and I have to allow mail in to my exchange server on port 25, I am using NAT/PAT. The only problem is that the ISP host's the mail on three servers. Can I create an access list to allow SMTP in for each of the servers IP address or if I just allow all smtp...
Thanks for the reply!
I tried changing the ACL but it is still the same. When logged onto the console I can ping the outside interface but not the gateway. Could it be a NAT/PAT issue.. How do I allow all traffic just to test, this would do no harm as I am on a test network.
