Cisco Switching/Routing :: 1921 Default Password Invalid
Apr 17, 2013
I bought a cisco router last week. The reseller said it is a brand new one. However, when I try to set it with console cable connecting to PC, the default password does not work. I tried to use control+break to get access to rommon for password recovery. The tera term pro displayed nothing at all! In thin case, what should I do to setup the router? Dose the reset button in the back work to restore the router to factory setting(which means i can use default username and password)?

I just received a Catalyst 2960-C (WS-C2960C-8TC-L R) switch and I am unable to sign into its web GUI in order to configure it. I've tried both the Cisco Network Assistant and Internet Explorer and I am unable to log in either way. The documentation provided by Cisco states that the default password is simply cisco and that a username is unnecessary. Needless to say, it doesn't work. I've also Googled for other default passwords (such as cisco-cisco as the username-password), none of which worked either. I've also tried resetting the switch back to its factory default a few times.

We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability
delay down 1 up 1
!
track 20 rtr 2 reachability
delay down 1 up 1
ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?

I did some testing in WLC in our company wireless network.However, after my 3 hours testing, I had tried to login WLC again by GUI and SSH. The admin username and password does not work any more. All Read only and Guest Account did not work as well.Is any one had this issue before? Is there a restriction for access to WCL per 3 hours or one day? By the way, I did not change any password.

I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]

Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?

My company has an 881-w ISR that provides wireless and wired network functions for our small office (about 20 users). I was attempting to create a new V LAN (another story), and was able to create the V LAN (4) and assign it a new IP. However, when i came in today, and when i attempted to connect to the ISR, the serial console started spewing this over and over:
*Feb 8 13:31:32.479: %SYS-2-MALLOCFAIL: Memory allocation of 8 bytes failed from 0x81528DF0, alignment 0
Pool: Processor Free: 131305952 Cause: Interrupt level allocation
Alternate Pool: I/O Free: 17850656 Invalid memory action (malloc) at interrupt level -Traceback= 0x820168A0z 0x82E4
-Process= "<interrupt level>", ipl= 4 -Traceback= 0x81FF6FC8z 0x820168D0z 0x82E49944z 0x81528DF4z 0x800C3AF8z 0x800C4760z 0x810A1208z 0x810A6F8Cz 0x810BA9E0z 0x810BACBCz 0x80241A24z 0x8025ADE8z 0x8025E2F8z 0x8030ACD4z 0x804E1518z 0x80310368z
[code]....
Now, I did leave the console session up overnight, as that's the only thing that I can think of. As expected, our service contract had expired. I did reboot the ISR, and I am looking to see if this can be fixed, or symptomatic of a larger issue, and time to replace? At this point i can't even get it to stop, and thus cannot log in.

I have a d-link router model dir 655.To activate my laptop all that was required was to enter the wps pin.I just purchased an apple ipod touch which is asking for a password.I first tried the wps pin.Then I went to the d-link website and put in my model #.It gave me an ip address which brought up a page where there was a choice admin or user.I picked user.The second choice was to put in a password which I did.The Ipod still says password invalid.I tried numerous times.

I will be installing two Cisco 1921 Routers to connnect a T1 between two offices. We are changing out our current AdTran routers as we would like to bridge three VLAN's across the T1 link. I followed the instructions at (URL) shtml to the best of my ability and my two Gigabit Ethernet ports are tied into a bridged virtual interface (BVI1). I then assigned a IP to BVI1 and another to my Serial0/0/0 then made a route to get to the other side of the T1 and a defualt route out our proxy. What I want to do now is setup QoS to make sure my voice data gets priority.
I setup a QoS ACL called "Voice" with the TCP and UDP source and destination ports that our phone system uses. I then setup a QoS policy on the Serial0/0/0 outgoing interface called "VoiceTraffic" and under the "match" list I match DSCP 46 or my "Voice" access rule. For the action I turned on "Queuing" and set it up for LLQ at 50%. Does this sound about right? Is there anything els eI can setup? I tried ot setup something else on the ethernet side but because they have the BVI I can't. I read some article sin this forum that said I could still apply QoS to the GigabitEthernet ports even if they are in the bridge group but it doens't let me do that.

I have configured DHCP snooping on a WS-3560G-48PS running IOS 12.2(58)SE2 ipservicesk9 variant.When I enable DHCP snooping clients don't get IP addresses, when DHCP snooping is disabled, everything works fine.I have set up a SPAN port and run a capture (attached) on the traffic. Wireshark notes the Seconds elapsed field appeared to be encoded in little-endian but only on some packets. Apart from that, I can see nothing wrong with the DHCP Offer responses from my DHCP server.Attachment config.txt contains the interesting parts of the configuration. Please note g0/32 has been set to ARP inspection trust as without working DHCP snooping it would require a static bind.Is there any way of figuring out which option can't be parsed? Is there a way to force forwarding of unparsable DHCP packets while still running DHCP snooping?

I am setting up a new 1921 for a public library and I am running into a problem and I bet I am missing something simple. All the internal stuff works and I can ping the outside IP on the 1921 but can't go any further to the internet. The 1921 has the 2 gig ethernet ports, 0/0 is connected to a DSL getting DHCP settings fine from the DSL modem. The other gig ethernet port 0/1 is running the inside network and its function fine, I have a server on it and other clients and they can ping and get dhcp settings etc.I've pasted the config output below and IP addresses of the main actors.

I have already ordered a Cisco ISR 1921/K9. but as i read on Cisco website, it is written that Cisco 1921/K9 only support (IP SLA Responder) feature.
I don't know actually what is sla- responder. but our requirement is we will connect that Router 1921/K9 into 2-ISP links and i want to enable IP- SLA probes on that router so that it can track both the routes into those isp links. so my question is does CISCO 1921/K9 have the support for what i need ?How about Cisco 1921-SEC/K9 ?

Im having some major issues with my new setup. I have a Cisco Router (1921ISR) that is connected to the internet through a t1. In addition to that is another cable modem. Each of these are connected to my firebox through an external interface.My router is on the 10.1.10.X network. My internal network is 192.168.1.X I have several NAT statements on my router pointing to 10.1.10.X addresses. These addresses are defined on my firebox as seconday external addresses and I am SNAT'ing them to 192.168.1.X addresses on my local LAN.This is mostly working well for everything. However, there is an FTP I am connecting to through the a VPN on the cisco that will not connect. The source is a 192.168.1.X address.

I have a ASA 5520 which is intended to use as a VPN for clients using PDA, I think the PDA is a very old product that the VPN only support CHAP/ MS- CHAP, but seems it cannot connect the VPN, it will prompt "invalid username and password" (but in fact the username and password is valid when using PAP), below is the log i captured from the ASDM when the PDA is connecting the VPN. when i tried to connect it in windows PC, I also have the same issue if the VPN setting is using MS-CHAP, if I choose PAP, it can connect with no problem. But the PDA has no option of PAP. [code]

When I attempt to sign in though the Kindle says my password is invalid or it says it just can not connect. I have gone over and checked what I hope are all the settings but to no avail.
