Cisco WAN :: 7600 TDM Cross-connect?
Oct 11, 2011
I'm trying to find a single device that can both handle Q-in-Q VLAN trunk termination and also TDM cross connects between DS0's on a multi-channel T1 card and DS0's on a multi-channel DS-3 card. I'm looking at a Cisco 7606-S with SUP720's. If I install a 7600-SIP-200 or 7600-SIP-400 with both a SPA-2XCT3/DS0 (channelized T3 card) and a SPA-8XCHT1/E1 (channelized T1 card) will I be able to TDM cross connect the DS0's between the cards? Is there a limit on the number of TDM cross connects? Also, I noticed the CMM cards are EOL. Ideally we'd like to terminate PRI's into the 7606 and run H.323. We'd like to pass voice calls to CUCM and TDM switch FAX calls (via H.323 dial-peer) to a given CAS DS0 on the SPA-2XCT3/DS0. Is this doable with any of the current cards? If not, then we'll stick to the configuration in the first paragraph and only have the 7606 handle the TDM cross connects.

I can connect with no problems through my ordinary internet cable but not when I instead connect it to the router and I put a cable between the router and computer. Then a red cross appears between my "Network" and my "Internet" and it says "there may be a problem with your domain name server" when I try to repair it. I can access the router settings by going to 192.168.1.1 but I don't know what to change. It's a Linksys WRT54GL and I'm on a windows vista. I've tried stuff like reseting the router and doing ipconfig /flushdns but no success.

I am trying to implement in the lab. I have 2 switches 3550 and 3750. my questions are:
1. why i can't see vlans in the running config on switch 3750 even after i created 3 vlans?
2. the 3750 is power over ethernet switch and i am trying to connect 3550 and 3750 thru cross over cable trunk link and the ports doesn't show up no light nothing. is it the right way of cabling.

Am running Cat6 cable to my cellar. I plan to run a face plate in the walls of all rooms where there will be an ethernet connection. Originally when I did this in a previous house I wired two rooms together i.e. a face plate in one room and the other end a face plate. I did a cross over cable for this so when connecting anything at the other end it would talk to the device in the other room i.e. room A NAS straight through to face plate, room B PS3 straight through to face plate for example.However as I will be connecting multiple rooms together in to a patch panel then switch / router how will this then work? For all rooms where there is face plate do I crossover all cable to the patch panel or straight through? If straight through to the patch are my patch leads then cross overs to the switch?

I have an ASA-5505. [code] I have an Exchange server on the 10.10.10.0 network. I need to be able to allow Active-Sync and OWA from the Guest WiFi through to the Exchange server on the 10.10.10.0 network. The Guest Wi-Fi uses external DNS so traffic is going out to the Internet and getting an IP address which is of course assigned to the Outside interface abd trying to come back in on that interface.How do I make this do what I need? How do I setup the rules to allow this traffic?

We have cross domain trust relationship established and I have added the user group in our ACS 5.1. we are using Active directory as an external Identity store. Also I have created a rule in the 'Access polices' to allow the user group. From the cross domain, I use abc@xxx.xyz as a user id, but I get this error message 13036 Selected Shell Profile is DenyAccess.

We are configuring a new EMC VNX, and plan to use Ether channel with our 3750x stack. We would like to configure it for both additional bandwidth and for redundancy. What is the best configuration to use? Should we trunk the channel or use switch port mode access, and use channel-group on or protocol LACP (which state active or passive)?

Long time since I have had to configure a router and have a small project
Here is what I have in a simple diagram:
PC(static IP)--to--Switch--to--(Ethernet0 int, WIC0)1721 router(FastEthernet0 int, built-in)--to--Switch--to--PC(DHCP)
I need static IP PC to be able to ping the DHCP client. Static IP units 10.1.1.x/16, DHCP clients 10.1.3.x/16.
I have found these overlap and thus give errors and will even shutdown the interface if I enable certain things like routing or bridging.
So I gather I need to change one interface IP range, which would be the DHCP side, I need to stay 10.1.1.x/16 for static side.

I have reinstalled windows 7 on my laptop. the problem is that the wi-fi internet is not working anymore. The network icon in the system tray shows a cross sign with a red color. I cant seem to be able to find a solution. Tried all the solutions listed in the forum. When i connect the lan cable directly into the laptop the internet works fine. But as soon as i remove it the cross sign again comes and i cant have internet access. I am having an Atheros Ar9285 Wireless Network Adapter installed in my device manager and everything is fine there with no ? or ! marks. I am using a Belkin router with in built modem.

I have a new 877 that I am using for internet traffic for 3-4 internet only devices.I also have a clean network that i want to insure no cross contamination. However I plan on rolling this out to many sites, but for management I was hoping to set up a reverse telnet to the console port from our one of my clean switches. which should allow me to keep the units seperated and allow me to manage changes etc remotely. Unfortunatly there is no Aux port on the clean switch (3560). Is there still a way to acheive this? can i configure one of the ethernet ports to connect to the console of the 877?

We have a pair of WS-C3750X-24T-S in a stack and four WS-C2960S-48TS-L in a stack of their own. There is not really anything too fancy configured (no special VLAN configuration/trunks or etc.) but the 3750 do have two ports configured as L3 for routing. We are not trying to use those ports for EtherChannel. These devices are running IOS 12.2(55)SE3 Essentially we are attempting to make an EtherChannel group using port 48 on all four of the 2960's in their stack (four ports). On the 3750 we will configure an EtherChannel group using port 23 and 24 on both switches (four ports). We then connect them up to form a four member EtherChannel.The ports on both ends are configured as mode ON and they are all 1Gb ports. I elected mode on because I understand at least one of the EtherChannel protocols will not work cross stack. What I would like to ask is whether the above configuration is possible or are we hitting some sort of limitation of EtherChannel cross stack, etc..? I cannot find anything to suggest this configration is invalid, but thought I would ask to see if I missed something in the EtherChannel articles.

I am running out of ports on a 4507R and would like to use a 3750G-24TS stack that I already have to expand capacity. Is it possible to configure EtherChannel between the 4507R and the 3750G stack and if so what is the best way to do it? without LACP, with active-active mode LACP or passive-active mode LACP...
This is what I have in mind:On the 4507R side I would like to use interface GigabitEthernet3/5 and interface GigabitEthernet4/5 where modules 3 and 4 on the 4507R are "6 1000BaseX (GBIC) (WS-X4306-GB)". On the 3750G side I would like to use ports 28 on both switches in the stack which are equipped with Cisco GLC-T= 1000BASE-T SFP transceiver module for Category 5 copper wire with RJ-45 connector. [URL] Cross-Stack EtherChannel Without PAgP or LACP should look like this:
3750switchstackA(config)#interface gigabitethernet 1/0/28
3750switchstackA(config-if)#channel-group 1 mode on
3750switchstackA(config-if)#switchport trunk encapsulation dot1q
3750switchstackA(config-if)#switchport mode trunk
3750switchstackA(config)#interface gigabitethernet 2/0/28
3750switchstackA(config-if)#channel-group 1 mode on
[code]....
is that what I should be doing? is there any benefit to the active-active mode LACP or passive-active mode LACP and which are applicable to the case above?

According to the following Cisco webpage, cross-stack 10-Gigabit EtherChannel is possible on the 3750 with up to two 10-Gigabit modules, using LACP: url...However, the webpage doesn't confirm if this functionality is restricted to a particular 3750 model, such as 3750E, or if it applies to all models. It also doesn't specify any particular IOS feature set. I've tried Cisco Software Advisor but it doesn't list this feature on either the 3750E or 3750-X. This is possible on the 2960-S switches (i.e. cross-stack 10gig EtherChannel)?

i want to realize a 20gb ring stp with 6 3750x stacked by 2. I want to install 2 3750x stacked configured in hsrp mode with other 2 3750 stacked. These 2 different stack are interconnected by a cross-stack ether channel 20Gb fiber. On the other side of the room i want to create a new stack with 2 3750x with cross-stack ether channel 20gb connected with the previous 2 stacks. So, in total 3 different cross-stack ether channel 20Gb stacks interconnected creating a ring stp of 20 Gb.

configuring EtherChannel between 3750-X cross-stack and 6509E switch. I use two ports on 3750s, and two ports on 6509. I just need it as a trunk. For some elusive reason one port on 3750 keeps being err-disabled, and one on 6509 notconnected.
Here is what I did so far.
3750
!
interface GigabitEthernet1/0/22
description ***VSS-RNOC-link***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2
[code]....
Problem with :
GigabitEthernet1/0/22 is down, line protocol is down (err-disabled)
GigabitEthernet2/1/29 is down, line protocol is down (notconnect)
I tried shutting them down, then no shutting them again. Didn't work.
