Cisco Switching/Routing :: IP SLA Between 2900 (15.0) And 2800 (12.4)?
Apr 11, 2013
I've problem with IP SLA probes between two different routers.2900 (c2900-universalk9_npe-mz.SPA.151-4.M4.bin) here is set "ip sla responder" only and 2800 (c2800nm-advipservicesk9-mz.124-24.T2.bin) here is set two type of tests "udp-jitter" and "icmp-jitter" - temporary, used to check for availability of 2900 router.As a result, I've what udp-jitter doesn't work at the same time icmp-jitter test is OK.Here are the settings of IP SLA tests
ip sla 281
icmp-jitter 172.25.28.1 source-ip 192.168.28.6 num-packets 100
tos 128
frequency 120
ip sla schedule 281 life forever start-time after 00:05:45

Site A, site B, site C, site D is connected using leased line each other. We are using Cisco 1800, 2800 and 2900. Each site also have Internet connection using ADSL connected to firewall, we are using pix 501 and ASA 5510.My question is, can i use the existing ADSL line to be use as a backup line if the leased line is down on any of the site??And i want it to trigger itself, once the leased line is down, the firewall UP the backup line? something like that..

Cisco C2960S IOS:12.2(55)SE5
Cisco C3560X IOS: 12.2(55)SE3
The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
2960:
mls qos map policed-dscp 0 10 18 24 46 to 8
mls qos map cos-dscp 0 8 16 24 32 46 48 56
mls qos srr-queue output cos-map queue 1 threshold 3 4 5
mls qos srr-queue output cos-map queue 2 threshold 1 2
mls qos srr-queue output cos-map queue 2 threshold 2 3
mls qos srr-queue output cos-map queue 2 threshold 3 6 7
[code].....
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.

I have a few old 2600 routers (2621, different IOS's) which I'm now replacing for new one's from the 2900 series (2901, Version 15.1(4)M4).In my configuration I have two IP addresses in my LAN interface and I have HSRP configured within the secondary IP subnet range. It would be something like this:
interface GigabitEthernet0/1
ip address 172.x.x.x x.x.x.x secondary
ip address 10.z.z.z z.z.z.z
[Code].....
Now, in the new 2900 routers, my interface configuration hasn't changed however I can see that the hello packets are now sent with the source within the respective HSRP IP subnet so I had to edit my acl for that:
permit udp 172.x.x.x x.x.x.x host 224.0.0.2 eq 1985
Is there a way I can force the HSRP to work as it previously did in the old IOS's?

I have a 2900 router at branch office. This router has a 4 port switch card and two gigabyte ports. The gigabyte port is use for wan connection and the 4 port switch card is use for lan connection. I have two separate networks on my lan side. (network 1 and network 2)
I have assigned port 0,1 of the switch card to vlan1 for network 1 Ports 2,3 of the switch card is assigned vlan 20 for network 2
My problem is I would like to applied a bandwidth restriction for all data coming out from vlan20 capping same to 384 kb.
Note I do not want use QOS because this will only kickin when saturation occurs,

I know we can use copy & Paste, my questions are:
1. Before that, do I need to wipe out the existing confi on the brand new switch?
2. About using TFTP, how does this new switch connects to the TFTP? Does it mean I have to assign a real IP and put it on our network?

we ordered a data e-delivery PAK L-SL-29-DATA-K9= (FOR A 2900 SERIES ROUTER) but after we received the PAK we discovered that the client actually has a 1900 router. Any easiest way of rectifying this mistake so that we can use the PAK on a 1900 series router?

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.

I have asked to test an VPN phone for home Users. I have a BT adsl broadband at home which is going into a cisco 2900 switch. Port One is connect to the computer port 3 is connected to the Avaya VPN phone this work's. The quality is not very good, so the question is could I have qos on Port 3 which is connected to the phone?

I just purchased a used Catalyst 2900 XL switch and have not been succesful in connecting to the console via minicom 2.5 running on Ubuntu 12.04 or 11.10, I don’t even get junk charecters in the terminal or echo on input. The switch passes POST according to the LEDs on the front and the network ports are fucntional for switching purpouses.
I’m using a Prolific PL2303 USB-Serial adapter, which works with minicom to console into another device. I’ve tried every baud rate available and tried combonations of hardware flow control, software flow control, and niether.I’ve tested the pinout of the console cable and all pins map correctly according to Cisco spec.I’ve also tried Cutecom, putty, and screen. I have not tried HyperTerminal because I do not use windows.Is it possible that the previous owner disabled console access? Do I need to reboot the switch each time I test a different baud rate?

I recently copied a configuration from a router 2800 to a 2900. After a power outage no one can connect outside of the network through the new router. Before the outage all was fine. I put back the old router and all is fine which eliminates any cable or switch error. I have the router totally disconnect. I notice the configuration is in place. My question is there any diagnostics that I can run to see if there is any hardware failure. It seems to boot up fine.

I am having a problem reaching a soho linksys e1000 router through a second hop cisco 2900 router.Here is a brief topology of the network: I am using OSPF area 100 for all networks except for
192.168.2.0 on R1 to E1000 which is RIPv2
R1 directly connects to R2 with a point-to-point serial on network 192.168.12.0 /30 with ip 192.168.1.13
R1 directly connects to a a switchport using network 192.168.2.0 /24 with ip 192.168.1.75
R3 directly connects to a switchport using network 192.168.1.128.0 /25 with ip 192.168.1.129
R3 directly connects to a different cisco router using ethernet on network 192.168.1.0 with ip 192.168.1.1
E1000 directly connects to a switchport using network 192.168.2.0 /24 with ip 192.168.2.1
The switch has a vlan ip on 192.168.1.128 /25?I can ping from R1 to E1000?I can ping from R3 to R1 192.168.2.75? I can't ping from R3 to E1000 192.168.2.1?show ip route on R2 indicates that network 192.168.2.0 is reachable via the serial connection on 192.168.1.12?I have redistributed rip to ospf area 100 and OSPF to RIP on R1?I am wondering why R1 can reach E1000 on network 192.168.2.0, and why R3 can reach R1s 192.168.2.0 newtork, but R3 can't reach the E1000.There is an R2 router than can reach R1 and also cannot reach E1000, but I assume it's for the same reasons R3 can't, so I've omitted the remainder of that topology for this question.

Had an odd issue that started up last few days.. Have a port on a cisco 2912 XL that keeps dropping (drops all packets) on a certain VLAN, but still passes others. Spanning-tree for that vlan says all ports are in forwarding status. VTP says that VLAN is still active.
This network is a little strange... 2924XL -> MotoPTP -> 2912XL -> Moto Canopy Array -> Some sites with cisco, some without all feed through canopy controller switch to single port (fa0/8) on 2912.
Getting a few of these on terminal monitoring, %RTD-1-ADDR_FLAP: FastEthernet0/8 relearning 5 addrs per min... Sometimes this is fa0/8, fa0/10, or fa0/1.
I'm thinking the switch has just gone nuts, cause fa0/1 is direct connected to a router used for VLAN1. fa0/8 is connected to a dumb switch on a canopy CMM as a trunk which i enabled bpdufilter on because of some spanning tree issues on VLAN1. fa0/10 is connected to canopy PTP back to the 2924 as a trunk. VLAN69s router is off the 2924. So there aren't really any possible alternate packet paths to this switch from another switch.
I also setup SPAN and captured all packets from fa0/8 and fa0/10 (seperately) and never seen packet storms of any kind on either VLAN1 or VLAN69.Further testing with debug, nothing on spanning tree, nothing on vtp, but on ethernet-controller addr I got some interesting results showing one mac moving from fa0/1 to fa0/8 and back to fa0/1 but it never moves, its the routers mac that is connected directly to fa0/1. Same with some macs on the other side of the PTP link saying they are bouncing from fa0/10 to fa0/8 and back to fa0/10 which isn't possible

The field engineer has a stand alone 24 port 2900 series switch that he has different equipment connected to and are segmented using VLANs. So for example, he's got ports 1-4 assigned to VLAN 10, 5-12 assigned to VLAN 20, 13-19 assigned to VLAN 30 and 20-24 assigned to VLAN 40. He would like all the gear on VLAN 30 to have the ablity to talk to all of the other VLANS, but VLAN 40 should not be allowed to talk with any other VLAN. Trunking would do no good here since the switch isn't connected to anything and you can only assign one VLAN per port.
Is there a way to do this within the stand alone switch? The only possible way I could think of would be to ensure that each VLAN has an assigned IP number (subnet) and doing this through access lists.

Is there any official Cisco reference to describe what is considered to be the highest acceptable production CPU load on 2800 routers? I found the document "Integrated Services Routers G2 - Performance Overview" that states at page 5,Most service providers set their CPU alarms to 60 or 65 percent. Many enterprise customers are comfortable running production networks with CPU around 70 or 75 percent.

I have a problem to create a VLAN with a Cisco 2801.,I need to have base ports FastEthernet 0 / 0 and FastEthernet 0 / 1, in the same VLAN.
Basically I'm trying to switch access redundacion, now I have redundant switches in which I have the servers, but if one of these switches fails, and,coincidentally is where I have connected the router, the server runs out of internet connection.,I idea is to connect the FastEthernet 0 / 0 to a switch, and FastEthernet 0 / 1, to the other switch,but I managed to have these two ports in the same vlan, in order to have a unique IP for both FastEthernet ports,As I can do this?. do is a lot of documents using the switchport command, but this command is not available in my router, I tried different IOS, and nothing.,currently I have the following IOS: c2801-adventerprisek9-mz.124-24.T6.bin

I have a 2800 router and tried so many ways to block the unwanted sites on my office network.Like access list ip based, null0 routing and policy map. Faced issues with below config
1. Creating Access-list. very difficulty to block the sites with https those sites will be opend, and we cant block all the IPs
2. Creating null0 routing. it also a bit deficult the block maximum sites because we can't fiend all IPs for those sites
3. Policy map.. with policy map we can only 1site we can block, but not more than one..
I heard that port based routing or port based access-list are the best ways to stop the websites in my local network..for this one i need to map the site to unsued ports then i need to null rouging or need to create the access-list.

c2800nm-advsecurityk9-mz.124-3i.bin
securedesktop-ios-3.1.1.45-k9.pkg
sslclient-win-1.1.4.176.pkg
Do I need these files for the upgrade or can i delete them when upgrading to 124-15.T13.bin. ?

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.
