Cisco Switching/Routing :: 3945 PBR Doesn't Appear To Be Working

May 1, 2013

I have a 3945 router with two interfaces connected to my firewall, one to the management interface and another to my dmz.  I'm running eigrp between all my network devices.  The problem I'm running into is when I try to ssh to the management interface of the 3945 the traffice hits the firewall, then goes right to the management interface as it should, but the return traffic is trying to use the dmz interface since that is how the router knows to get back to my computers network.  I created 2 route-maps to try and address this issue. [code] I've applied the MANAGE_IN route-map to all interfaces that might have inbound traffic destined for the management network and applied the MANAGE_OUT route-map to the management interface.  The MANAGE_IN policy appears to be functioning correctly, the MANAGE_OUT doesn't appear to be functioning correctly.  When I look at traffic from my host going to the management interface I see it still trying to return through the dmz interface.

Cisco WAN :: 3945 Chassis Doesn't Recognize HWIC-1GE-SFP

Apr 1, 2012

I just installed two of the HWIC-1GE-SFP cards in the CISCO3945 router but they are not recognized... I don't see any messages on the console output. I don't see them in the "show diag" command. I don't see new ports in the "show run" either... Is there some command I need to put in to activate them? Here is show version of my router:

Cisco Switching / Routing :: 3945 - Ability To NAT / At Least 8 RJ-45 Connections?

Nov 26, 2012

I currently have a Cisco 3945 router deployed and I am reaching the CPU's max during peak usage. The 3945 supports ~500Mbps Fast/CEF Switching and I need something at least double that capacity.

I need the ability to have at least 8 RJ-45 10/100/1000 connections. I also need the ability to NAT.

Cisco Switching/Routing :: 3945 / Using CBWFQ Before Reaching Interface Max Bandwidth

Jan 11, 2012

CBWFQ kicks in when the interface becomes congested and there is no available space in the queue but I need to find a solution to the scenario below:Im using a Gigabit interface on the 3945 Router that connects to the ISP. The ISP limits bandwidth to 60Mb so I need to make sure when I reach the limit of the 60Mb the router starts using the BW percentages defined in the policy-map using classes. any kind of traffic go out as it wants but as soon as the 60Mb limit is reached, the priorities defined by the traffic classes will kick in just as if the interface ran out of queues (as CBWFQ usually works).

Cisco Switching/Routing :: 3945 Loose Connection Between Router And Switch

Jun 29, 2012

We are having problems with a two router 3945 in HSRP and a switch 2960.The two routers are connected to the switch 2960 through differentes ports. The problem is that we loose connection between the router and the switch.When we excute the command: show cdp neighbor at router, it shows nothing.If we try to make ping to the 2960 switch it is no reachable.If we make ping to the other router 3945 it is not reachable.All other function of the router are o.k.We are attaching the IOS of the routers and switch 2960 and a document in which make reference to a BUG in which mention about arp overwrite due arp attack which produce DoS.

Cisco Switching/Routing :: Missing Commands Using DHCP / TFTP To Configure 3945 Router

Apr 10, 2012

I am using DHCP/TFTP to autoconfigure a 3945 router.  The router properly obtains an IP address and finds the correct TFTP server.  The issue lies in the download of the configuration file from the TFTP server.  The router downloads the file, gives the "Ok" message, and prompts you to press Return to get started.  When I view the running-config, several commands are missing from the Serial 0/0/0 section (HWIC-2T).  If I modify the config file on the TFTP server to use Serial 0/0/1 instead and repeat the process, the configuration file loads without any issues and Serial 0/0/1 has all of the commands.
 
I also tried moving syntax around in my config file, but the end result is still the same.  If I use Serial0/0/0 - I don't get all of the commands.  If I use Serial 0/0/1, I do.

Cisco Switching/Routing :: WS-C6509-E Doesn't Remove IPs From ARP

From, what we can see, whenever we try to clear arp-cache, it doesn't remove the IPs from the ARP. We've checked a bug in the IOS 12.2(33)SXH4 with the same issue, in version SXI4 is solved, but I have version SXI5, it is supposed to be fixed, from this caveat CSCtf16300, since it says it was fixed on 12.2(33)SXI4, it should be fixed on SXI5, right ?

Cisco Switching / Routing :: 3560 Doesn't Map DSCP Values

I've been working on a 3560 that doesn't seem to map dscp values to a new value: mls qos map dscp-mutation ToR1 22 24 to 46

On the router on the other side, I created an acl that matched on dscp 46, but it doesn't match on it. I've tried moving the mutation map to the ingress interface and I've tried setting dscp with a service policy instead of marking COS and using internal dscp. Where is the mutation map supposed to be placed: ingress or egress? Also, I added an entry in the acl on the router to see if I was mapping to dscp 24, and I am:

So it seems like the mutation map is being ignored completely. Any reason why?

Cisco Switching/Routing :: 6509 / Route-map Doesn't Get Any Hits

Dec 11, 2011

My network has two connections to a third party via links on two seperate ASA , one in location A and one in location B. The link in location A is the primary connection and the other in location B should be used by only two terminals (term1, term2) in location B. ASA are running OSPF and are redistributing static routes as metric-type 1 in OSPF. In order to achive the aforementioned goal, I have configured a route-map on ASA location B, that sets the metric for the route towards the third party to a high value (100). This way, all routers, even those in site B prefer the exit through location A (metric about 24).
 
I have checked that my routers correctly have the route to the 3rd party through location A, and the OSPF database has records for the network from both locations.In location B, I have configured the following route-map (on 6509)
 
route-map PREFER-LOCAL-ROUTER permit 10
match ip address XXX
set ip next hop locationB-ASA
 int vlanYYYY
ip policy route-map PREFER-LOCAL-ROUTER

[code]....
 
From the terminals (term1 and term2) I have tried a traceroute towards the 3rd party's subnet, but I don't get any match neither on the access-list nor on the route-map. Unfortunately I have no other way to test that my configuration is correct, since the application on the terminals, that should access the 3rd party network, is not currently running.
 
I also addedd the statements below to the access-list, because of the test with tracert:
permit icmp host term1 route_to_3rd_party 0.0.255.255
permit icmp host term2 route_to_3rd_party 0.0.255.255
 
Nothing changed...Is there something wrong with the above config? Is there a chance that there is a problem with the IOS, that simply doesn't show any hits?

I tried to break the password with all the speeds and it shows garbage output. I tried to turn on the switch and hold control + break and it showed the text only with the speed 115200, but after I left holding and tried to type it showed only garbage again. Also I tried to copy text from the notepad to the hyper terminal.

Cisco Switching/Routing :: WAG54G2 Doesn't Support A Subnet Mask

Cisco Switching/Routing :: 3750 Switches Doesn't See Traffic From Other Network

we have three separated network segments going to one Cisco 3750 switch all is L2 .. from this switch is 100 mbit uplink.we need to apply some Qos mechanism not to saturate line by traffic from one network.. Configuration from various reason CANNOT be done on switch where 100Mbit line is terminated.. so all must be done on SW1,2,3..Correct me if iam wrond but as switches doesnt see traffic from other network iam affraid only think we can do  is limit bandwidth on links going into SW1,2,3 to 33 Mbit.I found commad srr-queue bandwidth limit.But links going to SWs are 1Gbit so if i force bandwidth to 10% (minimum what command allows) its  100 Mbit..If I force speed on those links to 100Mbit and than apply  srr-queue bandwidth limit to 30% doest it work.??. Will  srr-queue bandwidth limit speed to 30Mbit?? Or srr-queue bandwidth limit is calculated from maxim speed of interface?

When i look at the version i See that bootloader is still the old version 12.2.58. It seems that the bootloader doesn't geht upgraded and that's why the Switch can't Boot the new Image.
