Cisco WAN :: 887 - EIRGP Hellos Queuing And Not Sending On GRE Tunnel
Jun 29, 2011
I have just installed a new 887 in a branch office. Two GRE tunnels are configured back to our two head office routers. Only one of the tunnels is able to send EIGRP hellos successfully and hence, one tunnel adjacency is flapping after the RTO is maxed. Ive tried a few things but I'm totally at a loss now. I can see from debug eigrp packets that the hello is en queued and that Hellos are received from the tunnel endpoint, but the ACK is generated and queued also. There are no access lists or nat enabled on the tunnel interface and no outbound acls in place. General NAT/PAT is set for the Dialer int. Ive removed all crypto and any QOS although I don't think these would affect this anyway. Bear in mind that both tunnels originate at the Dialer and one is working fine.
The SH ip eigrp neigh is shown here
EIGRP-IPv4 Neighbors for AS(****)
H Address Interface Hold Up time SRTT RTO Q Seq
(sec) (ms) Cnt Num
1 172.20.80.1 Tu0 10 00:00:13 83 5000 1 1784719
0 172.21.80.1 Tu1 13 2d21h 79 474 0 1437249
At this point Im starting to think it could be an ISP issue?

For a customer I have configured a new ASA 5505 firewall with 8.42 software. I had to build 3 ipsec tunnels to different locations and firewalls. All tunnels are working except one. I have to translate the inside network 1 to 1 to a different private range before it is sent over the tunnel. Each host from network 192.168.133.0 /24 has to be translated to a 192.168.112.0 /24 host and then sent over the tunnel. (e.g. 192.168.133.22 translated to 192.168.112.22)

i have a question regarding egress queuing on cat6500 modules. e.g. WS-X 6704 has 1p7q4t is egress-modell. my goal is to limit the priority queue to 15% of the available bandwidth. i can put weights on the wrr-queues and limit their ressources: "wrr-queue bandwidth 50 20 15 0 0 0 0." but this isn´t possible for the priority-queue. only available command is "priority-queue queue-limit 15" but this only restricts the buffer to 15%.
at the end of the day i want to prevent that the wrr-queues don´t have remaining bandwidth when the priority-queue is saturated.
is there an easy way to restrict the bandwidth of the priority queue or do i have to implement additionally some kind of policing?

I have configured Priority Queueing in my Cisco 2911 Router. I have set queue list high, medium, normal and Low. But when I put show interface gi0/2, it is showing the queueing strategy is priority queueing but it is not showing the (size/max/drops) values.

NX-OS 5.0(3)N2(1)Nexus 7010N7K-M132XP-12 line cards.By default the linecards/system use only 2 egress queues for the 32 port M1 cards.
1p7q4t-out-pq1 (matches cos 5-7)1p7q4t-out-q-default (matches cos 0-4)Which really doesn't line up with what wanted so we modify the config on the default vdc to the following.
class-map type queuing match-any 1p7q4t-out-pq1
match cos 5
class-map type queuing match-any 1p7q4t-out-q2
match cos 7
class-map type queuing match-any 1p7q4t-out-q3
[Code]....
By modifying the default queues it's affected the default egress policy-map, and in order to function correctly, a custom default list needs to be setup. With the default egress policy, anything not in the above 4 queues gets dropped.
Why doesn't the output queue in the default policy map (out-q3) match the actual class-map name of 1p7q4t-out-q3Are my assumptions about the output discards correct relating to the fact there is no relevant mapping for the modified egress queues in the default system policyWhere in the config guide is this? I've seen some reference that infer it, but don't actually point it out. Why this is a system wide config item, rather than on a per vdc basis.

I need to get some low volume, interactive data, prioritized on frame relay PVCs across our network. I have followed the CBWFQ examples from cisco.com, but my test packets are still showing latency over 1 second. My lab set up has a corporate connected gateway router linked via FE to testrouter 50. TR51 has a T1 frame relay loop to another router acting as a frame relay switch. The other side of the FR switch has a 56k link to testrouter51. I am sourcing test pings from my desktop PC, that are marked as AF43, and leave at a rate of 1/second, when the response comes back in time. I am using a Smartbits to generate some default class traffic at a rate of about 56Kbps only in the 'outbound' direction, toward TR51, as this emulates a file copy from corporate to remote sites, that is causing the AF43 traffic to suffer. Here is the relevant config on the TR50 device:
class-map match-all rtu-data
match ip dscp af43
!
policy-map frame-56
class rtu-data
priority percent 20
class network-mgt-data
bandwidth percent 5(code)

We are planning to implement the following policy map for egress traffic on an Nexus 7000:
policy-map type queuing dd-1p3q1t-8e-out-10G class type queuing 1p3q1t-8e-out-pq1 priority level 1 shape percent 10 class type queuing 1p3q1t-8e-out-q2 bandwidth remaining percent 5 class type queuing 1p3q1t-8e-out-q3 bandwidth remaining percent 5 class type queuing 1p3q1t-8e-out-q-default bandwidth remaining percent 90
We are using two N7K's to which is one N5K connected through a vPC. From the N5k we use a port-channel with 4 * 10G. Two of this four ports are connected to on N7K and the other two are connected to the other N7K. On the n/K's we are using vPC.
My question now are:
1. Where i have to connect the policy map? To the port-channel or on each physical interface?
2. When i have to connect this policy to the port-channel, how does i have to set the shape percent, when i would like to reserve 10% from the 40G? Does i have to set the shape value to 5% on each N7K because vPC?

There are a few situations were I'd like to be able to use the locally configured account on a device but still have ACS in place.I want to complete this WITHOUT adding the locally configured account into ACS.I have tried setting the advanced option under Identity for if an account is not found to "Continue" however this causes the account to be allowed as long as a password is typed (any password, as long as its not blank).

Our computer is sending but not receiving packets. We've tried 3 different wi-fi adapters, and that wasn't the problem. We have no idea what's wrong? It won't pick up any wireless signals by the way, and it works fine while connected via Ethernet.

I'm looking for troubleshooting LMS 3.2.1 and the ping/ICMP traffic it transmits.A lot of my devices are receiving a lot more pings from LMS than I would have anticipated.I don't run PING sweeps in Device Discovery or CM-UT. I've even disabled DFM polling in a hope to trace the source of these PINGs. Any list of which modules use PINGs so I can turn them off and track down the offender.I really only want to manage the known devices I already have via SNMP alone. I don't require LMS to be PINGing for discovery or reachability purposes.

I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.

We have a ASA 5520 which is configured to send log files to an ftp server. It has been doing that until recently I found out that it stopped sending the logs on August 11. I can't remember what I have changed in the ASA config to make the ftp stop. I changed the ftp config to another server but it won't upload any log file.
What can I do to make the ASA save the log buffer to the ftp server again?

When I disconnect it from the wireless, then reconnect it, it immediately receives packets but won't send any.

The university I attend doesn't allow modems and routers, but me and my roommates desperately need wifi for our devices, otherwise they are being wasted sitting around. today I set up an ad hoc connection on my roommates laptop, but he brings his laptop places and when he's out, we have no wifi. I have my desktop computer, and I can leave it on all the time and I never leave with it, so I'd love to set up wifi on it, since it will be so much more convenient.
I brought my router from home, and ive gotten it to send out my computer's internet connection, but it brings me to the school's registration page, which I can not use, since routers are not allowed. Is there a way to use my desktop's ethernet connection and send out that internet connection through my router (it also needs to bypass the school network, somehow fooling it that my router is my computer (im guessing))? I have 2 ethernet jacks on my computer by the way.

I'm using Cisco 2100 cable modem. It worked fine until some time later where the Data Send & Receive LED's stopped blinking. A man came to check if the cable was the problem by replacing it, but it wasn't. He claims it might be related to the laptop. I have tried several times restarting it. (I'm using mobile broadband) I would really like fast rather than slow internet ( I was limited so now it's slow but free)
