Cisco Switching/Routing :: 7450 / ASR901 Only Support MSTP In The EVC Configuration?
Jun 20, 2012
I have RSTP rings consisting of Alcatel 7450's and Foundry FES switches. I want to insert Cisco ASR901's into these rings and have been testing in the lab. It appears that the ASR901's only support MSTP in the EVC configuration. So I would prefer to keep RSTP on the Alcatel and Foundry's and enable MSTP on only the ASR901's.
Topology is:7450-2 <=> Foundry-2 <=> ASR901-2 <=> Foundry-1 <=> ASR901-1<=> 7450-1 with a VPLS between the 7450's.
If I enable MSTP in the Foundry's, Alcatel and ASR901 everything works fine. If I keep RSTP on the Foundries and 7450's, then STP also works, with the exception of a Foundry-2 switch running RSTP, that is located between 2 ASR901's running MSTP. This switch does not seem to interact with the other switches (i.e. thinks it is the root bridge).Since there are mulitple MSTP boundary's, do the ASR901's need to be in different IST's/instances?

For a customer we want to deploy the Cisco ASR 901 and connect them to a E1 unframed connection. However I don't see in the documentation that unframed is described and I was wondering if the Cisco ASR 901 is supporting E1/T1 in unframed mode? [URL]

I'm trying to setup a GDOI based IPsec connection between a cisco AS901 (advanced Metro lic - asr901-universalk9-mz.152-2.SNI ) and a 7606-S.What I see is that the ASR901 is capable of decrypting the IPsec packet but I cannot encrypt the ICMP packet back, so the question is if the AS901 can support IPsec in software. What I could not find in the docs on CCO. [code]

I am just browsing and looking for a solution to converge my multi-vendor switched network and bring some redundancy to it as recently
we managed to get a redundant links. I have a need to change core switch to Cat3750G, which has Per-V LAN-RSTP+ on board, but tests have shown that it won't be compatible with some other proprietary per-V LAN RSTP solution other vendor's switches use currently.
So, I thought maybe standard-based MSTP design might do the trick. I've made some tests and got some weird and unstable switching result. I have two topology rings with a core switch in the center. Every ring has about 10 switches, so practically network diameter may vary from 5 switches (when spanning-tree converges in the center and I have a blocking port somewhere int the middle of the ring) to about 10-11 switches (if a I have link failure on any of ports right at the core switch). I disconnected one port from core switch to eliminate a possible switching loop while I will be configuring new MSTP design. Then I started enabling MSTP on all the switches staring from core Cat3750G to MSTP, one by one, placing all switches to the same MSTP region, and placing all V LAN's to default MSTI0(CIST) cause I don't need to organize any separate MSTP instances for every V LAN or for group of V LAN s. When I turned MSTP on on 7th or 8th switch in the chain (cause I had a physical chain when I disconnected one port out of redundant ring) I got all switches "flapping", storming and flooding the network with broadcasts. Even when I had one redundant port disabled.
I have no idea what I am doing wrong. I noticed that Cat3750G has an option that defines a possible network diameter which actually automatically changes some hello, max age etc. attributes according to diameter specified. When I defined a maximum network diameter of 7, if didn't change anything: I still have hello timer of 2 sec etc. I've been wondering if the maximum network diameter has something more than just a "variable" to fine tune hello timers etc? Maybe I won't be able to use MSTP in my network which might have diameter more that 7 switches. Or maybe it was a mistake of placing all the switches to the same region and all the v LAN s to the default MSTI0 (CIST) and I should configure one MSTI per V LAN or per some group of V LANs and subdivide my switches to few MSTP regions?
My topology briefly looks like this:
+--SW1----SW2----SW3---CORE---SW4---SW5--SW6---+
| | | |
+---SWxx---SWxx-----------+ +------SWxx-----SWxx----+
As I said, each "ring" has about 10 switches connected side by side.

I am position to migrate from CatOS 6509 switch to native IOS 6509 switch. long time ago, there was some site to convert automatically based on copy and paste onto the tool, but i can not find.
Does anybody know how to convert CatOS configuration to Native IOS configuration ? It is not IOS change, but it is configuration convert.

Does the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?

I am trying to configure MSTP on Layer-2 network at work. We have multiple switches connected on Wireless point-to-point links with redundent links.MSTP is configured with multiple regions. All the servers are located in RegionA and other regions are connected to RegionA via multiple links.
There are 3 SG-300-10 switches in RegionA --- SwitchA_1, SwitchA_2 and SwitchA_3.One of the simple regions (RegionB) has a single SF-300-08 switch (SwitchB) connected to SwitchA_2 via port e7 and SwitchA_3 via port e8. Hello Time, Forward Delay and Max Age are at their default values of 2, 15 and 20 respectively. The link between SwitchB (port e7) ---- SwitchA_2 is the primary link with cost 200,000 and the link between SwitchB (port e8) ---- SwitchA_3 is the backup link with cost 500,000.
The log on SwitchB is shows in the table below. As it is seen from the table there are frequent topology changes for very short duration (1-4 seconds) before the topology settles back to the configured one. (Primary link forwarding and secondary link blocking). During this time there have been no link failures reported.Same thing is also observed within RegionA (SwitchA_1, SwitchA_2 and SwitchA_3 are connected to each other).
How to stop these frequent topology changes? The topology changes within RegionA causes a lot of PPPoE sessions to reset and re-establish.Is there any way to find out what triggers these topology changes?

We have 3 WiFi links between 2 buildings, these links carry a main data network, a VOIP network and a CCTV network. Occasionally due to unestablished factors we loose one or other of the links for a short period (5mins to an hour). In order to give some redundancy I opted to use a pair of switches and utilize MSTP to give a low cost solution. I have installed an SF302-08P in one building and an SRW208G in the other building and connected ports 1-3 as trunk ports to the three wifi links on both. Ports 5-7 on both switches are set as access ports and connect to the respective networks within that building. MSTP region is set the same on both switches and the instances and VLANs are the same on both switches. I have set port priority and cost to force the three networks to use their own link until a failure occurs. Then within the MSTP instances I have set the path costs such that CCTV or MAIN failover to VOIP last of all. During testing on the bench using patch cables to simulate the wifi links all went well. Upon installation things got a little more difficult. The VOIP network seems to work well but the CCTV won't pass the video traffic until the SF302-08P is rebooted even though I could connect a PC and login to the CCTV devices from either direction. More serious though is no matter what I do the MAIN network will not pass traffic. The MSTP interface settings show the correct port states with (in the case of MAIN network - MSTP instance 3) Port 1 Alternate, Port 2 Discarding, Port 3 Forwarding and Port 7 Forwarding.However a pcap shows no traffic across the wifi link on VLAN 4 (MAIN) although Layer 1 must be ok as VLAN1 is fine. The only other factor that may be relevent could be the wifi units themselves as the CCTV and VOIP links use an older 2.4GHz bridge while the MAIN link uses a newer 5GHz bridge. The 2.4G units have no knowledge of STP while the 5G units are 802.1d aware but I'm sure I read somewhere that 802.1d devices will cause problems with RTSP or MSTP networks due to the BDPU message format compatability, therefore I left it disabled.

Coincidentally when i tried to configure router 877 as an adsl router i found that a vlan configuration is included. my question is what is the benefit of using vlans in router ??? i studied that we use it in switches for the purpose of network enhancment from broadcasts and netwrok segmentation. why we use vlans in routers ?

Does the 4500 support VSS (Virtual Switching System) ? On the official product overview page it says: 1.6 Terabits capacity with Virtual Switching System (hardware-ready)What means Hardware ready ? Does it mean that it supports VSS in the same manner as the 6500 ? The reason I'm asking this question is that I didn't find any info on the Internet about this. We would like to upgrade our network by interconnecting the 2 sites with Layer 2 redundant links (Layer 2 extension), but I'd like to use the both links in a load-balancing manner, which can be a real pain in the *** with STP. The choice is between 4500 and 3750 stackable core switches. The 6500s are very expensive.

I have a 3560G switch with c3560-advipservicesk9-mz.122-46.SE and 2 routers. The switch has vlans defined. I want to route all traffic on vlan 25 out of one of the routers exclusively. Here is what I have attempted:
-Set the SDM template to routing & reload
-Define an access-list for the v lan traffic
-Define the route-map
-Apply the route-map to the vlan interface
When I attempt the last step I receive the following syslog error:
%PLATFORM_PBR-3-UNSUPPORTED_RMAP: Route-map RM_IMDGuest not supported for Policy-Based Routing
Also, the route-map is removed from the vlan interface after this error is thrown. Im 99% confident that PBR is supported on this switch (am I wrong?). Here is the relevant show output:...
access-list 125 permit ip 192.168.25.0 0.0.0.255 any
route-map RM_IMDGuest permit 10
match ip address 125
set ip next-hop 192.168.5.3

We purchased ME 3400 switch and trying to implement it. But its quite surprising in the ME3400 configuration guide that the switch does not support VTP. When I checked in Feature navigator under feature "VTP" i could see ME3400 supports VTP. But when i get into CLI of ME3400, i am not getting any option of configuring VTP. I could see in some sites VMPS is supported in ME3400.
I would like to confirm the following:
1. Does VTP support present in ME3400 or not? If not, what would be the reason that it is not included in ME3400.
2. If not what is the alternative.
Network is already running VTP of around 30 switches.
