Cisco :: Out Of Band Management With New Routers (1941 And 2921) IOS 15.0?
May 16, 2011
Our out of band connections with the new routers (1941 & 2921) with the new IOS 15.0 are not working.
Here is our configs:
Router:
line aux 0 exec-timeout 3 0 modem InOut transport input all stopbits 1
Modem(D-Link):
at&fs0=1s2=127s37=9e1q1&c1&d2&s1&k0&r0&w
Here is an output of the debug command:
*May 17 05:02:14.206 UTC: TTY1: CTS went down on IDLE line*May 17 05:02:17.206 UTC: TTY1: CTS came up on IDLE line*May 17 05:02:22.206 UTC: TTY1: CTS went down on IDLE line*May 17 05:02:25.206 UTC: TTY1: DSR came up*May 17 05:02:25.206 UTC: tty1: Modem: IDLE->(unknown)*May 17 05:02:25.206 UTC: TTY1: EXEC creation*May 17 05:02:25.206 UTC: TTY1: create timer type 1, 30 seconds*May 17 05:02:25.674 UTC: TTY1: create timer type 10, 30 seconds*May 17 05:02:26.154 UTC: TTY1: pause timer type 10 (OK)*May 17 05:02:26.154 UTC: TTY1: resume timer type 10 (OK)*May 17 05:02:26.174 UTC: TTY1: pause timer type 10 (OK)*May 17 05:02:26.206 UTC: TTY1: DSR was dropped*May 17 05:02:26.206 UTC: TTY1: Set

I am having an issue authenticating users via 802.1x/EAP-TLS across an IPSec tunnel. I am using route-based VPN with SVTI configuration on a 2921 and 1941. I have the following settings defined:
- Under the tunnel interfaces:
- MTU 1390
- MSS 1350
- PMTUD
- Under the ingress LAN interface
- route-map to set the DNF bit to 0
- On the RADIUS Server (2008 NPS)
- Framed-MTU: 1300
This had been working for months until I got a call last week about users not being able to authenticate to our secured SSID. I fired up wireshark and also used my client monitor tool in my wireless NMS to watch what is going on. I see all of the access-request and access-challenge exchanges, but the final exchange never happens. In both captures you can see messages with id's 77-81, but message id 82 isn't shown in the wireshark capture, only fragments are. In the client monitor capture you can see that message id 82 is 1726 bytes in length. Now, if I capture packets on my local LAN, the 1726 byte packet is properly fragmented and users can authenticate just fine.
I have scoured the Internet trying to find a setting that I must have missed, but I can't. I've tried adjusting the Framed-MTU, all the way down to 1100.

I can not find any information about management port of Cisco ISR 2911, 2921 and so on. There is management port in specification of 2911 and 2921 and I do not know if this port can be as a simple Ethernet port – forward traffic in/out on L3.

I've got a 3750X, IOS 15.0 IP Base license, reset to factory defaults, and I want to use the FastEthernet0 out-of-band management port on the backside next to the console port. The idea is that this port should provide a management interface that does not participate in the routing table. Problem is, contrary to the documentation, that configuring an IP address on the interface does make it show up in 'show ip route'. So it's still part of the routing table. Also, I'm unable to find the commands to change this and set a default gateway for just the management interface. I'm pretty sure this has to be possible, I remember seeing something similar on an ASA once. The 3750 configuration guide on Cisco.com does not seem to mention it.I considered using VRF but it's an IP Base license, no VRF.

regarding to the out of band Management interface , if I configured an intervace vlan to be as a managment interface for one vdc ( the default vdc ), when I connected to this vdc via telnet , can I switch to any other vdc ? ( suppose that I have the Admin role which allows me to enter and config all the vdc's )If that is possible so that I dont have to make a dedicated managment ip for each VDC I need to do that only if I want to make vdc admin's account to allow some users to access specific vlans only , is that true ?

What is the point of it? It is not a remote console. If i reboot the switch i cannot get back to the out of band management port unless the switch is fully running. Is this only for security purposees? so all telnet/ssh is from an Out of band network?

i have: two nexus 5596 connected each other the mgmt0 is NOT in use SVI for keepalives with IP address and /30 netmask vpc-keepalives running over fiber in e1/1. this works well uplinks to datacenter distribution switch (Cat 6500 VSS) over fiber on port-channel 1 (e1/2 and e1/10), also carrying the management VLAN (vlan 14). SVI with an IP address for management purposes
I can't get this to work. i can ping my whole network from the nexus, but not the nexus from my network. also pinging inside the mgmt vlan is not possible.

I have a lab setup and I want to test a point-to-point connection between two 2921 routers in a lab environment, without going through an ISP. I have a HWIC-1DSU-T1= in each of the routers. I have already configured ip addresses to the router interfaces, eDo I need to set any CLOCK RATE or BANDWIDTH commands or anything like that, since my traffic will not actually be going through an ISP during this lab test?

I have 1941, 2901 ISR routers. I will use 3G backup when primary link (metro ethernet / G.SHDSL) goes down. Do I have to use Data License (SL-19-DATA-K9 / SL-29-DATA-K9) in order to switch back to 3G when primary link is not reachable) ?

I am doing a comparative between cisco and sonicwall routers. Which router would better fit me? i need it to support at least a 20MB internet connection in a datacenter and has to have a firewall included. I was thinking about a router 1941. What do you think ?

A small remote site is going to need a dedicated 10mb connection to our Main Campus. Probably an 10mb ELAN connection(not decided as of yet). The site will be small - no bigger than 2500 sq feet with small walls possibly. Only one VLAN will be needed and we won't need any voice applications or back-up WAN ports. The site will provide connectivity for approximately 15 people. I've been looking at the 800 series routers for a solution. Do you think the 860 with the built-in 802.11 AP will suffice? I have a couple of concerns:
Does the 860 have CLI management?Will I be able to create a secure, encrypted tunnel between the 860 and a 2811 router on our Main Campus side? The 2811 has a 10mb ELAN secure tunnel on one interface already. I will purchase another interface card for this new, remote site VPN connection.Will the built-in AP give me coverage for the sq footage? I understand that there are extenuating circumstances to be concidered but, generally speaking?
From the video spec I viewed, the presenter said it had "basic security". What does that actually mean? This concerns me, as I want to built a secure WAN connection.Finally, does the 800 series fit this application or are there other Cisco products I should consider?

Experiencing a strange issue with v3 hardware. After a short period of time, I cannot log into the web administration - either locally through standard port or remote through non-standard port get login prompt, enter correct username & password, page refreshes with blank background and first page (status?) never shows.power cycling the router restores access to the web administration page, for an uncertain period of time before it barfs again.
I was running older firmware, updated to newest 4.2.1.02 (?) and same problem. Only thing that is better is the internet didn't completely lock up when I tried to access the administration page, like it did on the older firmware.

setting up Rate Control in Bandwidth Management. It doesn't seem to work at all. I knew from some other Posts that I need to have IPS on and I do.. Is there something else I need to do.
My users are connected wirelessly to the router through three different SSIDs and I have 3 VLANS. I need to set some limitations on two of the LANS.

I have a DB750N Router (Model F9K1103V1) that upon initial set-up was able to see both the 2.4 GHz and 5 GHz bands. I then added a Range Extender (Model F9K1106v1 and was able to see both bands for a short period. Both the Router and the Extender have the latest firmware upgrades installed. I can no longer see the 5GHz band and have been unsuccessful at attempts to get it to appear on devices connected to my wireless network.

The Belkin N600 DB N+ Router. It has 2 seperate networks for optimum performance, how do i go about choosing which band I want to use? Under the Belkin desktop I can clearly see 2 SSID's. One shows 2.4 GHz SSID & network name and the other 5GHz SSID & network name. media. But when I pull up my wireless connections I only see 1 network.

I'm attempting to configure remote management (and, sometime soon, SNMP) for a newly-deployed WRVS4400N v.2.At the Basic Settings page, I enabled Remote Management, and left the port # at the default. Remotely I entered the public (static) IP for the router in the address bar of IE8 similar to this: 67.203.???.??:8080. IE8's response is, "The webpage cannot be displayed." I'm using a public wi-fi access point, and don't know how the local router is configured, so it's possible that the local router has a blocking rule in the firewall.I'll try again using another remote router that I manage.

I have a RVS4000 hardware v2 with firmware 2.0.2.7. I have a DSL modem in bridge mode and have the router set to PPPoE. Everything works fine except I want to use QOS which doesn't work fine. I have some vonage boxes set up on a switch set to port 1 trust mode is set to port and level 4 for highest priority. Port 2 I have on another switch set to priority 3. I tried turning bandwidth mangement on which doesn't seem to work at all so I don't even know if they QOS is even working. I set the max down stream and upstream provided after running a number of speed tests and setting it a little lower than my worst speed results. Once I did that I set up a rule for all traffic for rate control and set them just below the min and max I put in for isp bandwidth. I set the ip range from 192.168.1.100-190 this will cover anything that dhcp hands out and I also have a few statics set up on 192.168.1.180 and 181. However after enabling it I ran some speed tests and I still get full speed and the rules seem to be getting ignored.

Just brought another set of SRP521W, after changed the WAN setting to PPPOE, we unable to access the web management. The power/sys light will keep blink when trying to access the web management. We able to ping it. We tried the reset button but it did not work as well. Is that a way to upgrade the firmware without using the web management?

I have a brand new RV042 v3 that I just updated to the latest firmware (v4.2.1.02) and have stumbled across an anomaly... I can only access the router from the WAN port using port 80. I happen to have it set to port 8080, but that doesn't work; I have to use standard port 80.
I have two other RV042 units running older firmware and they work as expected and follow the port that is filled in. This one has me puzzled and wondering if this is a bug in the firmware.

i cannot access the web managemnet interface of this router from a different subnet.THe WAN interface is a 4G LTE connection,I have disabled both the SPI firewall and NAT and enabled remote management from any ip address but i cannot access the admin web page from a remote subnet.Doing a port scan of the routers WAN or LAN address i cannot see any ports open at all...its as if firewall or NAT is still enabled somehow.

I have a RV082.I need to disable the firewall, since firewalling is done better elsewhere.However disabling firewall Remote management on wan ip is forcefully enabled.I don't need Remote management, keeping it enabled is a security risk for my setup.I don't understand the rationale behind the choice to forcefully enable remote management if firewall is disabled.Is there a way to disable both firewall and remote management?Or at least a workaround?
I'm on firmware 2.0.0.19-tm on a probably v2 hardware. (Cannot find this info in the web configuration).This is not the newest even for v2 hw but I cannot afford to break it trying to upgrade the firmware.Moreover no release notes for firmware releases refers to a correction of firewall/remote management behavior.Is this behavior also in newer firmware releases?

I have the new XBOX 360 black N wireless adapter and the Linksys E3000 dual band router as I want to upgrade the network range and speed to N. I set up a unique SSID and passphrase (WPA2) for both 2.4GHz and 5GHz bands. My XBOX could connect to the 2.4GHz band network and could connect to XBOX Live. But when I configured all the settings and tried to connect to the 5GHz band network, but no luck. My XBOX just said it failed to connect. I was sure that I did type in the SSID and passphrase correctly. I still cannot figure out what went wrong. I even suspected either the wireless adapter or the router malfunctioned.

Model : TL-WDR3600
Hardware Version : V1
Firmware Version :
ISP : Centurylink
I'm using a WDR3600 router, and I'm having difficulty with getting internet access on the 5 GHz band. Right now the router is broadcasting in both 2.4 and 5 GHz as two separate APs. The 2.4 GHz band works perfectly fine, but when I connect to the 5 GHz band my device is not assigned an IP address and cannot connect to the internet (or even the router configuration page). Unfortunately, I don't have another device capable of accessing the 5 GHz band, so I can't check to see if the computer is at fault, but both the computer and the router have worked together with no problems before, and this computer has done fine in accessing other 5 GHz bands.
