Cisco 300 series switch VLANs
I've never used Mitel phones before so this might be a dumb question but is the PC port on the phone turned off? Your config looks good and if you have already tested the configuration and it worked then it shouldn't be the switch. -
Cisco 300 series switch VLANs
Hi, Have you tried the following command - "voice vlan state auto-enabled"? -
Need help with backup VTP Server
Hi, There are a few ways but the cheapest and easiest is HSRP/VRRP/GLBP. You will need to duplicate every core to switch connection on the backup core and a trunk allowing all vlans between cores but the config is very simple. Also, it is my personal preference and it requires more... -
asa not sending to syslog
Unless the IPS has just been installed and not configured correctly you should have no issues with it. You could add an event filter (Cisco) to allow syslogs through to the syslog server to verify but it might be something else. You could do a simple ACL log on the closest L3 device to the...- stubnski

asa not sending to syslog
Hi, Everything looks fine for the config. Has anything been added or changed between the firewall and the syslog server? Routing, IPS blocking, ACL on syslog server, etc.- stubnski

IP routing with multi-layer switch: what if you have *many* multi-layer switches?
Hi, You will need to configure each one separately and use routing protocols to update the route table. Here are a few links from Cisco about LAN design - here and [link http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Medium_Enterprise_Design_Profile/MEDP/chap2.html]here[/url] -
IP routing with multi-layer switch: what if you have *many* multi-layer switches?
Hi, No, you can have as many L3 switches in your network as you want. Every network is designed differently to meet the needs of the business. If your business requires you to have L3 routing in multiple places then design it that way. L2 is faster and cheaper than L3 so keep that in... -
telnet stopped working
Hi, Going along with what Vince mentioned, did the script logout of the telnet session properly or did it tie up all the VTY lines causing you to be unable to login? If it did tie up all the VTY lines, do you know if there is a timeout set? You can still console into the switch if the timeout... -
Design Principles
Hi, If the majority of the traffic will be contained within the 10GB switch, with only a small percentage of traffic going to the slower core/distribution layers then that is a valid design. If this is the case, you should look at QOS to shape or police your traffic as needed. You should... -
Setting up a voice and data vlan on a switch
--> I assume it's a kind of ignorance thing where they don't actually understand what's going on with the frame header. Vince - What is happening with the frame header? I am truly curious as I have gone from a Cisco phone world to a non-Cisco(polycom) phone world and the same setup works for... -
Setting up a voice and data vlan on a switch
Hi, --> if the dhcp server was a windows server would it then have to have two nic's installed?? No. You need to remember the "IP helper-address" that you configure in the layer 3 interface of the Vlan. What this command is doing is telling all devices on that particular vlan to route to... -
Setting up a voice and data vlan on a switch
Hi, I assume you are using Cisco switches? I have not tried this with Avaya phones but it works with Polycom. create two L3 vlans (along with it's L2 counterparts) on switch with IP helper address Enable LLDP globally on the switch. This will enable lldp on all ports. Configure switch port... -
Help with a new 4507
Hi, Here is a Link to recover from what you are experiencing. If, like Lerdalt asks, you haven't deleted the previous image from flash, you can boot from that image and save you some time. -
Can a 10 Gig SFP port talk to a 1 Gig GBIC port
The twingig converter just takes a 10G port and turns it into two 1G SFP ports. It is the SFP that specifies the optics. You can buy SC to LC fiber cables, and just make sure that SFP you buy matches the specs of your current GBIC. Alternatively, there are 1G to 10G converters but they can be... -

No more trophies for participating

input on a decision for a core purchase in next 30 days (4500, 6500, 6800)
We also looked into replacing our cores with 6500's this year and our Cisco reps stated that because the 6500 was so integrated into so many businesses (huge, big, and smaller big) they were certain the 6500's will be supported for at least another 10 years. Plus they haven't heard any rumors... -

Cisco L3 switch for new Gig-E Internet- Any suggestions?
--> I'm currently in a look-out for a Layer 3 switch to replace the current 3750... I won't be running any fancy routing such as BGP so no particular need for higher memory models. I do however think a 10-G ready port is a necessity. A L3 switch should be fine unless you are planning major...
