We have a Cisco 1841 router and checked something an unnusual (never seen before) routing table having L - local routes. if this an IOS bug or same as C - connected local routes.

I'm trying to troubleshoot one of our site today and can't seem to issue the show dsl interface command on a 1841 router. Does the same command is used for SHDSL or am I running with an IOS bug?

I have a Cisco 2811 and a Cisco 1841 and I cannot get these cards to show up. My IOS for the 1841 is c1841-spservicesk9-mz.124-6.T7 and my IOS for the 2811 is c2800nm-spservicesk9-mz.124-17. When I do a "sh diag" the cards come up as: "unknown daughter card WIC module is not supported/disabled in this slot".
VPN 1841, and static nat. I have to create VPN to connect to remote network, but problem is that they already use same subnet as mine. How to configure static nat on cisco 1841 so static nat will work and address will be translated in different IP when connection trough VPN.I have address 192.168.235.1 and I want to translate to 192.168.100.1,This 1841 is border router, and all VLNAs and VLANs routing is on 3650.
I have a Cisco 1841 with a DSL and 3G HWIC interface. I would like to setup the DSL as the primary link and then use the 3G as a backup interface. I am trying to accomplish this using the Floating Static routes with SLA object tracking.
I have tried various options, like having two tracked routes, one tracked route, changing administrative distances, multiple SLA's, etc etc.
My problem basically is that when the DSL (Dialer0) goes down and the 3G (Cellular0/1/0) takes over, that the SLA never changes back when the DSL is available again, so that the DSL can take over as the primary link again. [code]
I used the GRE tunnel site to site VPN with 2 cisco 1841 routers. Behind one of the router R1, I used cisco ASA 5510, now my vpn is connect between two routers, but from R2 other site cannot access to LAN behind the firewall. From R1, also cannot route to local network, from local network can access to R1, I think cause of NAT . So how to configure to route internal network from R1 & R2 with VPN.
I've got an existing Cisco 1841 connecting to a 10Mbps Internet Leased line. With my current setup I've configured PAT for internet access for my users, and we also have some servers on site which are assigned public ip addresses, these can be accessed from the internet. Now we have procured a Cisco 1921 ISR to replace the old 1841, when I connect the 1921 with an identical configuration in place of the old router, 2 things happen.
1) The users accessing the net via the nat are able to work without any inconvenience (good)
2) My servers which have public IP addresses are unable to reach the internet and subsequently I am unable to reach them via the internet (very bad)
There are no commands like route-map & ip sla monitor on my cisco 1841 router, its ios version is 12.4(T1). I have to configure load balancing and failover on this router but without these commands i cant do that.
This two interfaces are in the global route table because there is no vrf indication. These are for internet access (a simple adsl connection) Then, I have this interface in VRF named "lan123"
interface FastEthernet0/1.23 encapsulation dot1Q 123 ip vrf forwarding lan123 ip address 192.168.143.254 255.255.255.0 ip nat enable
Now the issue.If I write:
ip route vrf lan123 0.0.0.0 0.0.0.0 Dialer0
this works and, with nat, internet works. The question is why this works without the "global" keyword? I'm going from the vrf named "lan123" routing table to global table without the using of "global" keyword.
If I try to use:
ip route vrf lan123 0.0.0.0 0.0.0.0 Dialer0 global
Basically I have an internet router (1841ISR) with 1 internal (LAN) connection and 2 internet connections. What I want to do is route specific traffic for 3 of my internally hosted services (smtp, https, etc) through one internet connection (fa0/0) and then route all other traffic through the unmanaged/dynamic IP ADSL connection (Dialer 0).
I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.
Facing issue with 2960G switch , where its do not display "logging trap informational " in show running and show startup .where its showing all other levels from 0 to 5 and 7 after configuration and save commands. [code] after config getting saved , it do not shows in show runn or in show startup while for all other levels it do show the config lines .I tried the same on 12.55.SE release also but its same results . Is this a limitaion of this platform, is there any doc explaining the same for reference. [code]
I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
I am trying to see what traffic goes through a certain ACL so I specify a protocol instead of allow all IP traffic. So what I did is enabled logging with debugging on that ACL. When I right click on the ACL and show log, nothing shows up. But I see hits on the ACL.
I've added several switches and one WLC to my new NCS Prime box. I don't see them in the display. If I try to readd one, it says it already exists. What am I missing?
Trying to get a Cisco ASA 5505 to show me all the current dynamic PAT. (I don't want to see hard-coded port forwarding, just dynamic stuff the router is doing to allow various hosts on the network to talk to the WAN.)
I would like to know whether there is any command that shows the configuration of the wireless controller (5508) like when you upload the configuration file from the GUI of the WLC. In other words, I don't want to show me all the verbose running configuration as the "show running-config", but a brief configuration as for example described below: [code]
I have a solution of thre ACS.. one primary and two secondaries. My customer report me that in port of the switch where is connected the ACS show two mac address. [code]
In a 6500 or 7600 a 'show module' gives a run down on all the modules in the slots, their HW and SW versions and status. But I can't find a similar command in the ASR1006.
I have copied status codes from show ip bg command output and its explanation (from Cisco documentation site)., d and h (suppressed, dampened and history). I read somewhere that these are to control flapping routes. But not able to understand it completly.Raised this question in a couple of forums but didnt get a proper reply.The table entry is suppressed.??The table entry is dampened. ??The table entry history. The table entry is validThe table entry is the best entry to use for that network.
I have two MLS conected by 2 fast ethernet links f0/11 and f0/12 on both sides.I am trying to set up a layer 3 etherchannel using these two links . But when i see etherchannel summary, they dont show up as layer 3. Instead they show as layer 2.
Looking for a show command to display the actual physical Ram modules inside a 2911 router. I believe they come with 2x ram slots and I need to know if it has 1 ram stick or 2.show version displays the total amount of ram, but not if its 2x128 or 1x256 etc.This is also production gear so I cannot open it up and have a look until the scheduled downtime.
Is there a command that can show EVERYTHING that is configured on a router or switchSeems if you're looking to save enough information to completely swap out a device the run/start config isn't enough.Settings like VTP and MTU settings aren't shown in the config file ... there may be other configuration settings like thisAm I forced to just know to check those settings are is there a command that will show the running-config AND all these other settings that aren't in the config?
I've got a 5505 and I'm getting a DHCP address from a cable modem. How can I show the DNS that the ASA is getting? show int vlan 2 is only givving me the IP and net mask.
In a basic VPN l2l scenario using ezVPN, server behind NAT device, client using 3G. What would be the reason to have in the output of the show crypto ipsec sa, a current peer different from remote crypto endpoint on the server ?
I'm monitoring 2 ASA 5585-x firewalls (in HA mode) using Cisco Prime LMS 4.2.1. The LMS server is connected to the firewalls on the inside interface.
My issue is that I keep on receiving Alert messages on Fault Monitor for both ASA firewalls listing all interfaces (except inside interface) as unresponsive.
My thought is that since the LMS server is not able to ping other active interfaces, it generates these alert messages.
My query is whether I'm thinking right? If yes, how can I prevent these unwanted messages from showing in Fault Monitor?
The Cisco 887 doesn't support the show dsl command, what is the command that I need to use to display the speed my ADSL is operating at? On the Cisco 877 the command I use is show dsl int atm 0 but this doesn't work on the 887
i've got a Cisco 877 router connected to an ADSL link. i'm using the show dsl interface atm just to have a look on its performance. i've tried to search on Cisco website on how to interpret the output but a blog gave me more info [URL]. My question now is, what readings do i consider? is it on the left (ATU-R) or on the right (ATU-C)?
After some time no using Cisco ACS5.1, I still don't know how I can see all logged in users. I can see logging and check why an log in goes wrong, but in ACS 3.2 I just clicked on Reports and Activity and I could choose to see logged in users, or failed attempts, etc.
