Cisco Switching/Routing :: 6509 - Changing From PVST To Rapid-PVST
Dec 15, 2011As a part of a major network cleanup/standardization project I have been working on for several weeks, I am now looking at spanning-tree and trying to get my company into line with Cisco Best Practice. I currently have 3 switches in the data center that are spanning-tree root for different vlans. Before I changing vlan priorities in spanning-tree, I feel that I should change from PVST that everything is on now to Rapid-PVST. To minimize the momentary network disruptions from making the change, should I do the edge switches first and do the switches in the data center at the last ?
Related to this process is something that I want to do probably after the PVST to Rapid-PVST change. I am going to manually set the vlan priorities for each vlan on the main core switch. Assuming I set the vlan priority for each vlan on my main core switch (6509) to 4096, should I set the switch I want to be the backup to 8192 for each vlan and then set the edge switches to something like 12288 to keep them from getting up in the spanning-tree hierarchy and for general principle to leave nothing to chance ?

Cisco Switching/Routing :: 3750 Adjusting Rapid PVST Timers
Jan 18, 2012We have two L3 3750 switches running HSRP and routing for various Vlans on our corporate network. Rapid PVST is running across our entire WAN. We are introducing a third party solution for remote communications over MPLS. When interconnecting this equipment to our core network, we have experienced less than desirable failover times of 32 seconds and recovery times of 60 seconds. The vendors engineers are telling is that the interoperability between IEEE spanning tree and Rapid PVST is the culprit.
They are suggesting two scenarios - either converting our corporate network to MST (which I prefer not to do but provides us the fastest fail/recovery times) or adjust the timers on our Rapid PVST forwarding timer to 4 seconds. What would the implications be to change these timers on our network, and if I choose to do this, do I only do it at the core (on the two devices that would become root bridge)? I have been doing some reading that says to not mess with the timers, but nowhere do I see reasons why.
Cisco Switching/Routing :: 28672 Two Root Bridges VLAN1 Rapid-pvst
Apr 1, 2013I have two locations DC and Corp connected to each other via Point to Point Circuit. I have forced the two core switches setup as GLBP pair to be primary and secondary for certain VLAN's including VLAN1.I have a switch in our Corporate office 3750 which is where the point to point circuit terminates. VLAN1 SVI is manually shut on that switch. Also the priority on VLAN1 is increased manually like this, "spanning-tree vlan 1 priority 28672".
Now the issue is that the Primarey Root Bridge in the DC is the root bridge for VLAN 1. But this other switch 3750 in our corporate office also is a root bridge for VLAN1. [code]
Cisco Switching/Routing :: Configure 7600 Ethertype

Cisco Switching/Routing :: 7600 / ES20+ Configure Global Command Mls Qos
Dec 18, 2012ES20+ QoS. As I understand for these cards QoS is MQC; i.e. similar to that of normal WAN cards
1- If i have 7600 with ES+ card only then I dont need to configure global command "mls qos" and the concept of trust boundries "mls qos trust dscp" will not exist , correct ?
2- For below output, why "show mls qos queuing" is giving an O/P similar to that of WS-X6xxx LAN modules.Also why it is WRR when scheduling is not configured.I expected that command will not work with this module as it is similar to WAN modules.
Cisco Switching/Routing :: 3750 - RSTP Not So Rapid

Cisco Switching/Routing :: 3750-X / Rapid Spanning Tree Inconsistent?
May 12, 2013I have two switches claiming to be the root bridge for the same vlans. The 3750-X stack was configured to be the root for vlans present and the 2960S was brought online over the weekend to replace another one. This is the command I used to attempt and make the 3750-X stack the root
spanning-tree vlan 1-2,10,50,101,200,900,999 root primary diameter 4
The IOS converted that to this

Cisco Switching/Routing :: 3750 - Rapid Spanning Tree In Access Layer?
Apr 9, 2012My colleague and I have been having a discussion about using rapid spanning tree in the access layer. Most of our infrastructure has been migrated to a routed access layer with 3750s.
The idea was brought up to configure the switches with rapid PVST. On the surface, it seems like a better idea, faster convergence, in the event that spanning tree ends up being used for some reason. My colleague prefers sticking with standard PVST. His argument is that, in the event of a layer 2 loop, some consumer-level switches filter out BPDUs and if the control plane is overwhelmed, the shorter timers of rapid PVST just puts that much more of a burden on the CPU trying to regain control, whereas with standard PVST it will have around 20 seconds before it starts to engage. (It may still be overwhelmed, but the longer timer delays the additional burden.) He says he's seen this problem with rapid PVST and that his opinion is backed up by our Cisco rep. (I haven't spoken to him yet.)
In our model, it should be very rare -- pretty much never -- that we would layer 2 span another switch off of our access stack.
One suggestion I saw is to use BPDU Guard, which is a good suggestion as well.
But we have had experiences with overloading the control plane on a 3750. I believe that concern is valid. If the CPU can't service spanning tree. But I'm interested in hearing about other experiences people have had in terms of rapid spanning tree in the access layer, end users plugging in unauthorized devices and creating loops, and the effects when using rapid spanning tree vs standard spanning tree.
Cisco Switching/Routing :: 6850 Pvst Alternate Block Avoidance
Mar 14, 2013I have an alcatel 6850 switch connected to a 3750. Two connections (cables) are used between the switches. The two connections from the alcatel are in different vlans 10 and 60 , but the cisco ones are in the same vlan ie 1 (I know not best practice but keep with it ). The cisco cables are connected into port 1 and 4. Port 1 is forwarding and 4 is blocking. The 3750 is configured with basic default pvst configuration.The alcatel is the root bridge. As can be realised traffic from alcatel on vlan 10 cannot pass traffic to the 3750, This was established by the spt seeing the same mac from the root bridge therefore blocking port 4.To stop this from blocking in this scenario I was going to use bpdufilter.

Feb 22, 2012Stange problem which I encountered today, I have a Cisco 2960 which is connected to a netgear. The switch started showing itself in CDP and was running STP. I checked the cables physically today and noted 3 uplinks to the netgear, all port on the Cisco active and forwarding and green lights.
The Cisco was running STP, I changed it to R-PVST and the lights on the Cisco went crazy and I got the message port flapping on the switch but the switch did not block any ports (all ports on same vlan).
There after I changed it back to stp and the switch blocked the other up links apart from one.
Sure R-PVST is far superior than STP?

Cisco Switching/Routing :: 7600 High CPU Switch Processor And DFCs
Nov 16, 2011I am a little stuck trying to troubleshoot unusually high cpu on 7600 Platform.This has been going on for many hours and not been causing a problem, but this doesn't seem replicated in our network and I am concerned about the cause.I have attached some output below, and disabled netflow on interfaces to free some switching CPU. How to track the cause of this? We only have routing protocols and 5 static routes to Null 0, so I cant see how this can be a route loop, but willing to stand corrected. Routes are learned from BGP with OSPF/MPLS internally on the network. This switch also connects to access switches on RIP and EIGRP.
No change has been made to this device when this problem started to occur so I am suspecting something about the traffic has changed or there is a rougue user? [code]

View 2 Replies View RelatedCisco Switching/Routing :: 7600 Static Route ECMP Failover?
Apr 29, 2012I have run into a problem testing static route failovers using ECMP. I have an edge device (SUT) that has 2 NIC interfaces to an internal Loopback. Each NIC is a unique Gi port on an 7609 VLAN tagged with unique IP subnets. The 7600 is configured to route the loopback via the 2 NIC. I am using CEF in the network for other traffic performance testing. Using an external sniffer we can verify that when a ping is initiated externall to the SUT loopback a specific path is selected by the router.
Ping host ------Network-----7609 Gi1/21 (172.16.110.9)-----------SUT Nic1 (172.16.110.10)
| |
| -------Loopback 137.168.68.114/32
| |
7609 Gi2/21 (172.16.110.73)------------SUT Nic2 (172.16.110.74)
[code]....
Now, when the selected path is taken out of server (pulling cable for example), the 7609 is not clearing the routing table to indicate that particular path is down and failing over to the secondary path. Other things I have noticed is the show ip cef still shows both peers as well as the arp table but the interface shows down (show interface gi1/21 for example). I am running 15.1. My understanding is that since the ports are directly connected to the router, the ports should be detected as down and any association of the IP for the down port should removed. This should trigger the static route to update the static route for the end destination to use the second path and traffic should continue.
