There is a Suttle sam v8m voice distribution module installed. Looks exactly like the one in this user manual:Page 5 of 8, Wiring Diagram.URL,However, there is NO Sam D8 switch below installed in the wiring closet. The Cat 5 cables from the home outlets enter the wiring closet and plug directly into the Sam V8m.Can a comcast modem be connected to the Shuttle Sam V8m to make the Cat 5 outlets hot? Or, does the Sam D8 (or similar) need to be installed?

My first option seems to be either purchase an IPServices license for the stack of 3750E switches, but i am thinking this will require us to license all three switches in the stack. The second option i am looking at is to do the WCCP configuration on the 2800 router we have on the edge. The problem is both Gig ports are in use, one going to the firewall and the second going to the ISP. My first question would be, which option is better in terms of manging as well as cost of implementing it.The second question is, if WCCP on the router is a better option, what is the add on module i should be looking to get to add the additional ports to hook up the Websense cache.

Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: iso.3.6.1.4.1.9.2.1.55.a.b.c.d (where a.b.c.d is the server IP)
I have also tried the method similar to that for Cat 3550 switches where you create a table of entries to define the transfer paramaters then activate the transfer (I think the CISCO-CONFIG-COPY-MIB)
e.g.
[URL]
C:>snmpset -v 1 -c private <device name> ccCopyProtocol.<random number> integer 1 ! 1 = tftpccCopySourceFileType.<Random number> integer 1 ! 1 = networkFileccCopyDestFileType.<Random number> integer 3 ! 3 = startup & 4 = runningccCopyServerAddress.<Random number> ipaddress "<server ip address>"ccCopyFileName. <Random number> octetstring "<file name>"ccCopyEntryRowStatus.<Random number> integer 4 ! 4 = createAndGo, or 1 = Active
To write net have the source as running (4) and the dest as network (1)
ccCopySourceFileType.<Random number> integer 4
ccCopyDestFileType.<Random number> integer 1
Clean up at the end - destroy .14 with the value of 6.
example output : -

We have recently implemented Windows Deployment Services on our local network, but everytime we do a multicast image deployment the network get flooded to point of total saturation.
We have Netgear switches and a Cisco 2800 series router. IGMP Snooping has been enabled on all Switches, however, we are unsure on how to implement multicasting on the router.
The whole network is flat - no VLANs over than the default VLAN1. We only want multicasting to work within our local network and does not need to go out the other side of the router as that is the connection to the internet.
How to get the Cisco router configured properly to enable multicasting to not flood the network. It seems that even if we were to image 4 PCs using multicast this is enough to completely get the network flooded.
Also, am I right in thinking that IGMP needs to be enabled on all of the Switches?
I hav a laptop conecteted to the internet with comcast service and a netgear wireless router that works fine. but bought a desktop and when i hook it to the router i get no internet. im running windows 7 ultimate on both machines. i am gettin a thing saying unidentified network in my network settings and i called comcast whent through resetting the modem and router with them and nothing then they tell me i have to pay them to run another machine of of my router this is ridiculas i have the machine pluged into the port on the router with anethernet cable everything is hooked up right i know this im pretty computer savy as ive built many machines in the past.

View 2 Replies View RelatedI've got a ASUS AC66 router plugged into my Comcast cable modem (regular dumb modem), it's running the Merlin (OEM-modified) firmware.I've got a Netgear 3400 router flashed with DD-WRT (latest build), it's a replacement for another N router that died on me.
Anyways, I went to set client bridge like always. Main router is 192.168.1.1 so I set DD-WRT router as 192.168.1.2, set the wireless modes to client bridge with matching SSIDs for my 2.4/5GHz radios, input the correct security keys on the security page (AES), then I put the router in router mode (from gateway) Basically, I followed the instructions on DD-WRT's website, which worked perfectly until the other router died.
This time around as soon as the DD-WRT router reboots with its bridge information saved it immediately causes some sort of conflict on my network and kills the internet and all network connections. All devices lose their IP address. It's like the DD-WRT router is somehow shutting down the network and my default router.
My neighbor is using my Belkin Router the basic one and has comcast. We both use his internet and have had no problems until the past 3 days. He just got the home phone service from comcast and the phone line is setup through the modem. Ever since comcast came to his apartment and set this up the home phone service to his modem the router is connected but there is no internet access. What is going on and how can I fix this. He has an HP with windows Vista and I have a Toshiba Satellite L675 that has Windows 7 Home premium edition on it.

Seem that only one of the routers will get an ip assigned from Comcast.Is there a way to have one ISP cable modem and create two different home networks with the two linksys routers, thus two separate independent networks?

I have an ARRIS Docsys3 modem from Comcast which has a built in WiFi router. I also have a DIR-655. The Modem is in my office and I have a 100' Ethernet cable running through my attic to my front room where the dir-655 is located.
I use the DIR for WiFi as well I have it connected to my TV and Xbox.I use the ARRIS Modem for WiFi as well I have it connected to another Xbox and a Desktop computer.I want to have everything on 1 network, Dir-655 uses IP address 192.168.0.1-100 and the ARRIS uses ranges 10.0.0.1-100. I want to be able to connect to the dir-655 and have the IP for that connection join up with the 10.0.0... network so that I will be able to transfer files freely throughout the network.
I want everything on one network. Right now when I connect a laptop to the DIR-655, I can not access the printer that is connected to the Desktop on the ARRIS modem. I have to connect to the ARRIS modems WiFi to then use the printer on the desktop.Likewise, I want to use the media extender on the Xbox connected to the DIR-655 with the Desktop connected the the ARRIS modem, but I can not because of the to different networks.
Every day for the past week my Internet access goes down. I have a netgear router connected to Comcast modem. I have to reset the modem then the router constantly and it gets irritating. I called comcast and they say reset them. But why should I have to constantly reset.... Sometimes I just ignore it and it comes back up later... what is going on??
View 1 Replies View RelatedComcast had us unplug our modem in order to upgrade to their new faster speed. now our wireless router won't work. We've reset the router twice. we can set up the wireless network but we cannot connect to it. The connection last for about 5 minutes and then we get an error, cannot read IP address. Comcast says it is not their problem and linksys says they can't assist either.

We have an MPLS network to a half dozen remote sites. At our main location we have a 2800 series router. In the routers config are the following lines for QOS. When I go to the routers on the other end of the MPLS, none of them are configured with these same policies. Would these not be in the running config of the 1800 series routers, or is this not setup correct and this should be removed?

I'm trying to turn off SSH version 1 & 2 to pass PCI compliance. Problem is, I cannot touch the VPN link between the two offices. I'm afraid the PKI certificate used for the VPN will be deleted if i zeroize the RSA key which seems to be the only way to stop the router responding on port 22.
Here is the stuff from the running config related to the crypto map:
crypto isakmp policy 1
encr 3des
authentication pre-share
group 2
[ code].....
I'm only CCNA so I'm not even sure if the certificate or RSA key is being used for the VPN link, but I can't tell from the running config that zeroizing it would be a good idea and not break the VPN. I'm open to other ways of disabling SSH, as we are able to just connect using a console cable. But it looks like denying port 22 with an access-list doesn't even stop the router from responding to the port.
My Cisco seems to be stuck when it boots up, with the following:

View 8 Replies View RelatedIs there a way to set static routes per VLAN?Example VLAN 100 sends all traffic to 192.168.1.1 and VLAN 200 sends all traffic to 10.1.1.1. (2800 Series RTR)I have 5 networks that have their own gateway to the Internet via satellite link. Those networks run over the same infrastructure on separate VLANs. They frequently send traffic to each other, which gets sent over a slow SAT link. I introduced a router to the network and would like to set all my hosts default gateway to the local routers sub-interface then have a static route that send all traffic that is not on one of my 5 networks back to that VLANs respective SAT modem to get routed out over the Internet.
View 4 Replies View RelatedIn a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
[URL]
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?

View 3 Replies View RelatedJust got home from the Comcast store with a $7 rented modem just to last me until I do research and purchase one. I realize that this modem has only one Ethernet port with no WiFi support so I have another PC and a laptop sitting idle because there's no internet access. Did a quick search using Comcast's authorized modem's list and all of them only have a single Ethernet port and no WiFi. Is there a modem with multiple Ethernet ports with built in WiFi? I am getting almost 20mbps with a download speed of 4mb/s which is a HUGE improvement over my ATT DSL service that I've had since forever at 3mbps with a download speed of 300kb/s. I have no idea what technical specifications to look for in a cable modem to get 100% of full potential speed from my service without disconnects or other various problems.
I have a ATT U-Verse router sitting here right now, I am wondering if I can somehow connect it to my Comcast modem. I tried to connect the ATT router into Comcast modem via Ethernet cable, but I couldn't get past the "Your DSL service is unavailable" in the browser, but in my desktop system tray, it shows I am connected to the internet. If I could use this router, I would rather spend money on a modem instead of getting a combo.
Life was great with my DIR-615 and Motorola Surf Board SB-5100 cable modem, but my D-Link refuses to recognize the Internet signal from the Thomson. The Comcast guy spent an hour trying to get it to work, but I'm stuck watching MLB.tv on a 24" monitor in a stiff office chair in my study, instead of on a 47" LCD in my living room. How can I force the DIR-615 to accept the Thomson ACG905? If you advise me to check settings or manually change them, please do not "assume" that I know how to access those settings.
