Cisco WAN :: ASR1004 Multi Frame-Relay Switching?
Dec 14, 2010
As U know cisco feature for frame-relay is creating mfr link and binding them to physical interfaces I did so but my MFR links doesn't get up?
PS. router is ASR1004
frame-relay switching

QoS on an MFR interface/subinterfaces. We have a remote site with two bundled T1's terminating on a 2951 router for a total bandwidth of 3072. The circuit is provided by Paetec and the subinterfaces are designated for internet and MPLS traffic respectively. The issue we are facing is with outbound voice quality. It seems that no matter how we apply QoS, either to the main MFR interface or the MFR subinterfaces, voice packets do not seem to be prioritized. We tried FRTS, which slowed the entire link down to a crawl, we tried applying a class map to the main interface as well as a service policy, none of which seemed to affect anything.
class-map match-all VOICE
match ip dscp ef
class-map match-any SIGNALING
match ip dscp af31
match ip dscp cs3 (code)

Network is 10.254.0.0/16
snag.gy/3Y8aN.jpg This is the network image.
This is my subnetted connections: http:[url]....
I can ping R2 to R5 but not R5 to R2. I have spent about 10 hours going through my network and code to no avail. I think it is the frame relay that's causing the error but not sure.. I just checked and I think R6 and R5 are not getting their OSPF updates by trying show ip route
Here are my configs: http:[url]....

I need to get some low volume, interactive data, prioritized on frame relay PVCs across our network. I have followed the CBWFQ examples from cisco.com, but my test packets are still showing latency over 1 second. My lab set up has a corporate connected gateway router linked via FE to testrouter 50. TR51 has a T1 frame relay loop to another router acting as a frame relay switch. The other side of the FR switch has a 56k link to testrouter51. I am sourcing test pings from my desktop PC, that are marked as AF43, and leave at a rate of 1/second, when the response comes back in time. I am using a Smartbits to generate some default class traffic at a rate of about 56Kbps only in the 'outbound' direction, toward TR51, as this emulates a file copy from corporate to remote sites, that is causing the AF43 traffic to suffer. Here is the relevant config on the TR50 device:
class-map match-all rtu-data
match ip dscp af43
!
policy-map frame-56
class rtu-data
priority percent 20
class network-mgt-data
bandwidth percent 5(code)

Main site have 8 departments and each department have 60 pc's,remaining sites each have 6 departments and in each department have 40 pc's and in the design of WAN connection you use frame relays and that is the 100% growng hosptals and clock speed is 64000 bits/sec and security must don't access the unautheraised users from out side....how can I do this?

Provider T1 handoff with two PVCs to their MPLS cloud to a 2911.One Internet PVC and one for the MPLS including a SIP trunk .
Is there a way to use QOS to have the router prioritize one PVC over the other.Always service the MPLS/SIP PVC over the Internet ONLY PVC?The MPLS/SIP PVC will have QOS for voice but needs to be prioritize.Other option will be to police down the Internet PVC to a value which will leave the required total Kb for the voice priority KB.(FR PIPQ works if the PVC is for voice only.)

I am having real problems trying to build resiliency into a hub and spoke frame relay scenario. I know the hub is a single point of failure. Is there any way to put some resilience into the network? There is 4 attached branch offices.

working through a lab and can't seem to configure frame relay on subints. I assume it's not supported but this seems basic; am I doing something wrong?

I have been trying to make rip work on this frame relay with multipoint configuration (hub and spoke) and I also configured a loopback interface on each of the routers and configured rip with the loopback address. I observed that the routers (cisco 3600 series) are not sending or receiving any RIP updates through their serial interfaces but are sending through loopback interfaces i configured (debug ip rip).I can ping all routers but cant ping their loopback interfaces because RIP updates are not sent or received by them.
R1#debug ip rip
RIP protocol debugging is on
R1#
*Mar 1 00:09:46.759: RIP: sending v2 update to 224.0.0.9 via Loopback1 (1.1.1.1)
*Mar 1 00:09:46.763: RIP: build update entries - suppressing null update
[code]....

I started studying yesterday for CCNP Route and I'm already stuck. Stupid Frame relay. Basic topology attached, 1 Hub, 2 spokes. I have EIGRP working correctly and each spoke can see all routes correctly. The Hub is on a Multipoint interface with split horizon turned off.

I've a home lab which consists of three 2610xm routers and I have configured two routers back to back with FR subinterfaces. The commands are used are;
R1
frame relay switching
int s0/0
encap FR
no sh
clock rate 64000
frame-relay intf-type dce
[code].....
Everything works great with this config and I know how to configure without lmi too. My question is more for the CCNA exam and fill the gaps in so to speak. The question is when you configure FR with static mappings and inverse arp do you need actual frame relay switches on the other side of the link or can I configure on my home labs routers. I know I am gonna try and configure this as well, but can I configure multipoint on my third router with a different physical interface. Like R1 with s0/0 to R2 s0/0 and R1 s0/1 to R3 s0/0 with subinterfaces.

I 'm trying to set up a home lab with a couple of 28XX and 2651XM series routers.I would like to simulate a frame-relay connection between HQ, Branch1 and Branch2 . All of them are conneced to a PSTN switch (2811 router) via T1 cross over cables. The connectivity is like this. [code] I have configured all the routers and FR switch with necessary configuration. However the link between HQ and Branch1 is not coming up. On both the routers I could see the line protocol is down.I have pasted the configuration below.[code]

I am installing an ASA 5520 and I have a problem on accepring the incoming traffic from an external office connected via Frame Relay.
On my OUTSIDE interface I have both the internet traffic and the external office traffic incoming. What comes from the external office is visible as 10.1.0.0/16.
I have to allow this traffic to enter the internal network, without any control. I would also keep the original IP address.
I have configured the Firewall but I don't know how to setup the NAT.

I'm looking to test fram relay connections in a lab environment i'm building at home. I have a couple of 2610 routers that are barebones and am looking to get some serial modules. Are (2) WIC-2T's all I would need to create those test connections? Also on a side note are the any modules for the 2610 that have fast ethernet connections. I would like to have that so I can create a router on a stick model off of the 2600's.

IOS 15.1(4)M1.
I am trying to setup my new 2901 running 15.1(4)M1 for frame realy via a VWIC3-1MFT-T1/E1 card. Now I have set up plenty of frame relay connections via older serial cards, but I just cannot find any documentation on how to do this on one of the new VWIC3-1MFT-T1/E1s. None of the commands I am used to seem to even exist. None of the
encapsulation frame-relay ietf
frame-relay interface-dlci 16 ietf
seems to be there. How to configure the card in IOS 15?

I have a 3845 running 12.4.13a which I want to upgrade to 12.4.24.After upgrade one of the interface that is configured for frame relay doesn't work anymore.In fact is the "service-module t1 timeslots" commands that can not be executed and the router throws that error.I tested this behaviour on two 3845s and the result is the same.Is this a bug or is an workaround for it?

Transitioning from 3825 to 3945 (OS is 15.0(1r)M13 c3900-universalk9-mz.SPA.151-4.m4). Turning on FDL on the 3825 was easy but the same command on the 3945 doesn't work.

I have a NM-1CE1U working on my router 2600 , configured with frame-relay . But seems it does not work on my router 2811. I have check that the replacement is HWIC-1CE1T1-PRI , right ？
But the problem is these two modules have different interface type , I want to keep my cable interface type and find one module card working on 2800 or 2900 router , can configure frame-relay.

I've had a read through the docs for the 3750 series switches, but nothing that definately says that jumbo frame routing will work on a SVI.One part specifically I'd like clarification on is:The default maximum transmission unit (MTU) size for frames received and sent on all interfaces on the switch or switch stack is 1500 bytes. You can change the MTU size to support switched jumbo frames on all Gigabit Ethernet and 10-Gigabit Ethernet interfaces and to support routed frames on all routed ports. It says supported routed frames on all routed ports, but this in the past has meant physical ports, and not Virtual ones.

I have a pair of N7K's in vPC topology with some FEXs attached. I am looking into enabling Jumbo frame on the N7K as well as the FEX. I understand Jumbo frame is enabled globally by default.
My question is I have some interfaces in a port-channel that I need jumbo frame enabled. Do I enable it at the port-channel interface or at the physical interface ? and is the change disruptive to the network ? I am running NX-OS 6.0.2.

I've got a problem with an ASR1004 running "asr1000rp2-adventerprisek9.03.02.00.S.151-1.S.bin".
When I'm performing extended ping tests using a tclsh script i'm geting this error message:
ASR_X1A2#ping 172.27.1.250
% Authorization failed.
When i'm pinging 12 diffrent destinations this happens to about 3 of them.
Checking the logs I found this:
Apr 24 19:42:56.071: %SSH-4-SSH2_UNEXPECTED_MSG: Unexpected message type has arrived. Terminating the connection
In my entire backbone this is happening only in this equipment, I've checked the connection between my ASR and the TACACS and it's OK, no packet loss. CPU and MEM are OK too.

Is there a way to configure a switch (3550, 3560,3750) to disable a switch port if it has not been used for a specified time period such as weeks or months. Say you want the switch to disable switch ports that have been "abandoned".

Lets say i have 2 3750 switches stacked via backend stack cables. Now if a packet needs to go from 1 switch in the stack to second switch in the stack, will it travel via stack cable or do we need to connect both switches via uplink ports (ethernet or sfp). I tried reading datasheet but it no wheres mention the actual frame path between switches in stack.

our C3750 like the one described here [URL]
We have the port on the switch set like this:
switchport port-security maximum 25
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
In case a device connected to the port is inactive for more than 2 minues ( aging time ) the first frame/packet the device generates arrives to the port on the switch, but the switch does not forward it to the appropriate port ( discards it or whatever ).
So far I tested on
1 30 WS-C3750E-24PD 15.0(2)SE2 C3750E-IPBASEK9-M
2 30 WS-C3750E-24PD 15.0(2)SE2 C3750E-IPBASEK9-M
3 52 WS-C3750G-48PS 15.0(2)SE2 C3750-IPBASEK9-M
[Code].....
When we remove port security from the port, it works perfectly fine, as expected.
It seems this is not HW or IOS version related. It seems it is not a stack synchronization issue, it does not matter if a device is connected to the first or other stack member. I tested on C3560 too, here there are no problems, so seems it is 3750 related.

I am trying to get an understanding of some behaviour I am seeing on my N7Ks regarding DHCP relay.I have two identically configured Vlans interfaces both configured with the same two dhcp relay servers in the same order. The only difference between the two vlans is that one is HSRP active on the A side switch and the other is active on B side switch. All clients in Vlan136 (active on B side) are getting DHCP leases from the first of the two dhcp relay servers configured while all clients on Vlan 137 (active on A side) are getting DHCP leases from the second of the two dhcp relay servers. I would expect that all clients on both vlans would get leases from the first relay server configured unless that device was unavailable.
