The SIP Media Inactivity Timer feature enables Cisco gateways to monitor and disconnect VoIP calls if no Real-Time Control Protocol (RTCP) packets are received within a configurable time period.
When RTCP reports are not received by a Cisco gateway, the SIP Media Inactivity Timer feature releases the hung session and its network resources in an orderly manner. These network resources include the gateway digital signal processor (DSP) and time-division multiplexing (TDM) channel resources that are utilized by the hung sessions. Because call signaling is sent to tear down the call, any stateful SIP proxies involved in the call are also notified to clear the state that they have associated with the hung session. The call is also cleared back through the TDM port so that any attached TDM switching equipment also clears its resources.

Clear channel codec

Hi Experts, I've an issue with Clear-Channel codec.
I've a SIP Trunk between an AS5400 HPX and a Cisco 1760. I would use this connection to manage ISDN data modem calls with 64 Kbit/s Unrestricted Digital Information capability.
This is the scenario:
PSTN ---> AS5400 HPX -----------> C1760 ----> ISDN DEVICES
When arrives a call from PSTN, the AS5400 sends a SIP INVITE to C1760 like this:
INVITE sip:****@10.25.100.77:5060 SIP/2.0

I've noted that the SDP of C1760 uses a different format to indicate clear channel.
AS5400: a=rtpmap:125 G.nX64/8000
C1760: a=rtpmap:125 X-CCD/8000
Is this the issue?
Is there a way to internetworking the problem?
Thanks in advanced.

I'm afraid there is no way beside updating the 1760 to the same IOS as the AS5400 - and that may not be possible because the 1760 is obsolete.
You could change the rtp numeric mapping, but not the codec description, and that's where the problem lies.
In any case, it's better to terminate ISDN on the 5400 rather than trying to relay over IP across dissimilar systems without the required timing guarantees.

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis

We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.

Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,
Nagendra

The difference of the IEEE802.1x Auth between Cisco Routers and Catalyst switches

Hello
I am investigating the difference of the IEEE802.1x Auth between Routers and Switches.
Basically dot1x auth is availlable on Catalyst Switches. however if I want to check to
PortBased Multi-Auth , MAC address Auth and any certification Auth with this feature,
Is it possible to integrate into Cisco Router such as Cisco 891F ?
In my opinion Cisco891F is also available to use basic IEEE802.1x but if it compares with Catalyst switches such as Cat3560X
I think there might be any unsupported feature on Cisco 891F.
I appreciate any information. thank you very much in advance.

Many time in interviews asked comaprison between cisco routers and switches that i was answerless bcoz i dont have much knowledge about that.Can anyone provide me the compariosin sheet of the same.how are the cisco devices differ with each other how much Bandwidth each routres support and Etc...
Ummmm ... The most common question I get is "what is the difference between a router and a switch".
However, if you get a question like this, then my impression to this line of questioning are:
1. The candidate they are looking for has in-depth knowledge of routers and switches. And I mean IN-DEPTH!;
2. They are not looking for a candidate. They just want to stroke their ego. There is not alot of people who can give you the "names and numbers" of routers and switches at a snap of a finger. And if you do happen to know the answer, then and there, then expect a tougher follow-up question.

Mobility between Cisco WLC and Meraki(other vendor)

Is it possible that users can roam between Cisco WLC and other vendor wireless gear? Meraki keeps saying it is possible.
They keep saying it is a IEEE feature and everone should support but I do not understand how?

While theoretically possible with the adoption of capwap, it would require all the manufacturers to follow the specs exactly the same. Kind of like hearding cats, not impossible, but highly unlikely.. That's just my opinion

VPN between cisco WRVS4400N and EdgeMarc

Hi Experts
Please help me.
Is it possible to create VPN between cisco WRVS4400N and EdgeMarc appliance.
Regards,
Ejaz

Hi Ejaz
I don't expect any cisco folks that answer this community to be expert on EdgeMarc, but i may be wrong..
We employ a open standard IPSec implementation.
Here is the open source document that relates to the RV220W.
http://www.cisco.com/en/US/docs/routers/csbr/rv220w/open_source/OSD_RV220W_78-19892-02.pdf
The question could have been, have you asked EsgeMarc if they wiork with open standard based IPSec implemations on our routers.
I would prefer you look at the RV220W if possible, which is a relatively young product.
I am guessing since you can source a product from Disti, try one and see if it works.
The beauty of buying from a Cisco Disti Partner, is they they have a returns policy. Check out that policy, if you wish and keep the packaging and try out your application.
Answered a question with someone trying to form a IPSec link to a OEM firewall/ IPSec gateway ..it worked. so give your application a try

Difference between Cisco DCNM and CISCO Fabric Manager

Hello Everyone,
I am new to Cisco SAN and just would like to know the differences between cisco DCNM and Cisco Fabric manager and which one is latest as of now.

Hi Viany,
Fabric Manager was renamed DCNM starting at 5.2.
Fabric Manager only monitors SAN Fabrics, while DCNM 5.2 and above can monitor both SAN Fabrics and Ethernet LANs.

Routing issue between Cisco device and Virtual machine

Hi Guys,
We have two local subnets in a virtualized environment, subnet 1 has a VM operating as a firewall, we would like all traffic for subnet 2 to go via VM on subnet 1, this will police traffic on subnet 2 and then reroute.
The infrastructure involved comprises,
Internet Edge Switch -> ASA -> Core Switch -> IBM Flex chassis
The Internet edge switch is directly connected between the ISP routers and the Cisco ASA firewall pair (A/S). The ASA is then connected to the Core switch. Connected from the core switch is an IBM Flex chassis, via a port channel (all vlans allowed)
The local subnets in question are as follows:
Vlan 101 (10.1.1.0/24)
Vlan 102 (10.2.1.0/24)
The VM in question has two NIC cards having IP address of both subnets.
NIC 1: 10.1.1.1
NIC 2: 10.2.1.1
We would like packets destined for 10.2.1.1 to land on 10.1.1.1 IP address. At the moment traffic for each vlan routes from the outside to their respective local subnets successfully, what we are having difficulty with is directing traffic for subnet 2 via subnet 1 VM firewall.
At the moment we have tried adding a static route on the core switch but it didn’t work
ip route 10.2.0.0 255.255.255.0 10.1.1.1
I will appreciate if you could share your knowledge and guide me how to achieve this goal.
Thanks in advance :-)

Hi,
I think for this to work you need a transit vlan between the VMs and the core switch. So, if you have 2 vlans on the VM (101 and 102) you use the VM switch to route between the vlans and in order to go outside the local vlans you would use the core switch. In this scenario you would not have an SVI (layer-3) interface on the core. The only thing that core will have is the layer-2 vlans (101 and102). You would than need a static route on the core switch to point to the transit vlan on the VM side.
so, for example, if the transit vlan is vlan 110 and the ip is 192.168.1.0/24
on the core you have static routes:
ip route 10.1.1.0/24 192.168.1.2 (VM side)
ip route 10.1.2.0/24 192.168.1.2 (VM side)
You also need an SVI for vlan 110 with ip address 192.168.1.1/24 on the core.
on the VM you need a default route to point to the core (192.168.1.1).
Is this what you are trying to do?

Inline Posture between Cisco ISE and Wireless LAN Controller

Hi,
I was looking into Cisco ISE solution for deploying NAC.
I have a question about the network topology.
In the user guide documents of cisco ISE, it is written that for Wireless LAN Controllers (WLC) and VPN devices, an additional server, Inline Posture, is needed.
However, in the following integration document, there is not an inline posture between WLC and Cisco ISE server.
https://supportforums.cisco.com/docs/DOC-18121
I want to know if Inline Posture is a requirement, if not a requirement, what are the benefits of having it between Cisco ISE Server and WLC.
Thanks & Regards

Port-channel Problem between Fabric Interconnect and N7K vPC

Dear all,
I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
This is my network topology for UCS Deployment
In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
Thanks,
Trung.

Thanks Matthew very much,
I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.
Thanks,
Trung.

GRE IPSec between Cisco 2811 and FortiGate 110C

Hello,
Does anybody know if it is possible to configure GRE IPSec tunnel between Cisco 2811 router and FortiGate 110C firewall? I know that FortiGate supports IPSec and GRE tunnels, but maybe somebody succeeded in establishing an IPSec GRE between those routers? Could you also give a link to the appropriate documentation if it is possible?

Hi,
You can configure the GRE tunnel on the 2811.
I'm aware that you can configure sort of a GRE tunnel on the Fortinet as well, but I have not seen a GRE tunnel between a Cisco and other vendor.
I've only seen GRE tunnels between Cisco devices (however I have not tried it to assure you that it will not work :-()

VLAN and STP compitability between Cisco 2950 and SRW2048

How Cisco 2950 and Linksys SRW2048 switches can be combined to work fine with more than one VLAN's and STP?? I want both switches to support three VLAN's and STP for loop free network.Can some body help me out to combine linksys and cisco switches to interconnect to form my Network???

I believe that the SRW2048 is a 48 port managed switch. The easiest way to set the VLAN and STP configuration of is to access the web utility of this switch via 192.168.1.254. You have to go to VLAN Management and he needs to create the VLANs. The default VLAN of the switch is VLAN 1. You need to create 2 more VLANs by choosing the VLAN IDs and the name you want for these VLANs.
After creating the VLANS, you need to determine the LAN of the switch you want to assign to each VLAN and the Trunk port or the port where you need to connect the SRW2048 to the Cisco 2950 switch. Go to the port setting and make this port as “truck”, and leave the other ports as “access”. Go to VLAN to ports and manually allocate the each LAN ports to the desired VLAN ID number. Take note that all ports that are members of VLAN1 should be “untagged” and the rest should be “tagged”. Save the settings you made.
The STP configuration for the SRW2048 can be found also in the web utility. Just go to the Spanning Tree tab and setup your desired STP configuration.
For the Cisco 2950, I am not quite sure on how to create these settings but I saw a useful link that might help you:
