My Cisco seems to be stuck when it boots up, with the following:
Upgrade ROMMON initalized
And it goes on with self comperessing image then an OK but then it starts loading again all over.
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.
I have Router 2800 series Global nating is configured on it.
ip nat inside source list 111 interface Dialer1 overload
!
access-list 111 deny ip 192.168.1.0 0.0.0.255 192.168.0.0 0.0.0.255
access-list 111 permit ip 192.168.1.0 0.0.0.255 any
My object is that i want give internet access only for few users ip E.g IPs addresses from range 192.168.1.0-10 can acess intenet access other all are deny.How i do this with ACL .
Is 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 RelatedI am trying to add WCCP to be configured for websense. 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.
View 8 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?
I have 6509 E. Actually what happen it last 3-4 times it reload its self and got stuck in rommon mode, i tried to boot it with boot by connecting a console cable on supervisor 720 2b. What and where is problem and why is stuck in rommon after reload.
View 11 Replies View RelatedWe 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?

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 received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
In a redundant Sup-6E setup, the following configuration is supported :
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
If you invoke shared backplane mode, the following configuration can also be supported:
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
Here's the command and information about the "shared-backplane" mode :- [URL]
Currently, we have 2 SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:
1- One will be used to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
My questions are:
1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?
The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.

View 5 Replies View RelatedI have just received a new Cisco 3750G Switch from my parent company. When attempting to install the switch, I discovered that it will not boot to CLI, only to the bootloader. After using the command boot, the switch attempts to boot the most current IOS version, but fails, stating "error loading XXXXXXXXXX.bin".
Obviously, I just need to get a functional version of the IOS onto the switch to boot, but the problem is exactly how can I do that? All (or most) the commands with which I am familiar are unavailable in the bootloader, so all methods known to me fail. Is there a simple way (maybe using the copy command?) to put the .tar or .bin file onto the flash?
I have a 2801 running c2801-spservicesk9-mz.124-3g.bin According to the Cisco IOS MIB locator the image supports OLD-CISCO-SYSTEM-MIB I have tried .1.3.6.1.4.1.9.2.1.55 etc to set server IP address and the filename string but without any luck.e.g.

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.

To write net have the source as running (4) and the dest as network (1)

Clean up at the end - destroy .14 with the value of 6.
