View 2 Replies View RelatedI encountered a problem migrating configuration from Cisco 4500 with IOS 12.2(53)SG4 to Cisco 6500-VSS with IOS 12.2(33)SXI7.
With 4500, we had 2 servers with JBoss running multicast to build up the cluster. They used 239.X.X.X multicast IP. There was no need to configure "ip igmp snooping vlan XX static XXXX.XXXX.XXXX interface X" neither static arp entry.
When we migrated to 6500 in VSS, we had to do:
mac-address-table static XXXX.XXXX.XXXX vlan XX interface X disable-snooping
With this command, the JBoss cluster worked well. The question is, ¿Is there any difference regarding IGMP in 4500 versus 6500?
What's the difference between a Catalyst 4500 and a Catalyst 4500E series chassis? I believe it has to to do with supporting PoE+? Are the blades in both series interchangeable?

View 7 Replies View Relatedsome of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?

Q. Does the Supervisor 720 support all existing Cisco Catalyst 6500 series interface and services module, protecting customer investments?
View 1 Replies View RelatedI am little confused about the location of FIB table and adjacency table in both cisco 6500 series and fixed ports switches .In case of 6500 series switches
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor,and the route processor performs the express forwarding. Use this CEF mode when line cards are not available for CEF switching, or when features are not compatible with distributed CEF."
If line cards do no support CEF, then FIB and adjacency tables are built and are located on route processor( control plane ). Data plane operations are implemented in software and route processor performs those operations.
Some Cisco switches actually use different hardware to control the different planes. For example, the Cisco Catalyst 6500 is a modular switch that uses the Multilayer Switch.Feature Card (MSFC) for control-plane operations, and the supervisor Policy Feature Card (PFC) for the data-plane operations.
Supervisor module has has MSFC and PFC. MSFC implements control plane operation where as PFC implements data plane operation.But the first paragraph says in Central cef mode, both data plane and control plane operations are implemented by route processor. [code]
Do these switches implement the Central mode cef in same way as mentioned above. i.e
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor and the route processor performs the express forwarding. Use this CEF mode whenline cards are not available for CEF switching, or when features are not compatible with distributed CEF."Or fixed ports switches such as 3750 implement data plane operation in hardware where FIB tabe and adjacency table are maintained on Data plane.

I am connecting power cable (series power cables) on 3750 stacks. i have connected them the same way the stack cables are connected i.e. fo rexample on a stack with 3 3750s:
1- fitst slot on fist switch connected the second slot last switch in the stack.
2- second slot/ port on the first switch to the first on second and seoncd on teh second switch to first on the third switch.
this how they are alway been stacked.Now, I need to connect power cables and I have followed the same method for stacks up to 4 switches. it seems that if a stack has more tham 4 switches, then the cabling will be dofferent!?I was wondering what will be on the cabling scheme for stacks more than 4 switches.
I have 3750 series with GIBICs ports I want to create 10 vlans with its sub-net and enable all vlans to access internet.
View 4 Replies View RelatedI am planning to migrate the core switch from cisco 3750 to Cisco catalysts 6513 switch. What could be the best approach to minimize the downtime or avoid disrupting the production. I have couple of thoughts, one method is to build the core and then replace the existing core, another option is to build the new switch as the second VTP server and once it recieves all the VTP information then disconnect the old server.

View 2 Replies View RelatedI'm thinking about using a 3750 stacking around 4 or 5 switches intead of using one 4500 series switch.
1-My first argument was concerning the budget (one 4500 instead of four or five 3750 in stack mode) ---- Here i think 4 or 5 stacked 3750 is cheap than one 4500
2- My second argument was about harware redundancing that i don't have with one 4500 and that i have with stack mode ----Here i have more hardware redundancing with 3750
3- The bug that we notice today in 2960 and 3750 and not in 4500
4- Simple to manage a 4500 compare to 3750 stack design
5- I was looking also for the one with best backplane ----Here i didn't have any infos concerning the best backplane between 4 or 5 stack 3750 and a 4500.

Is there any challenge to upgrade core switch 6500 series from Nexus 7009 which runs NxOS, because i have 3750X series switches connected at distribution and access layer in my network topology??
Is there any challenge if we place NxOS in core and IOS in distribution and Access layer??? how we are able to match sh run config in existing 6500 switch to Nexus 7009 NXOS?
I have 2 6504's running HSRP as my core. They are each etherchannel'd to my Datacenter switch (3750 Stack) -- see image below.The problem i a having is with the etherchannel status:
Core1 PO11 status w (waiting)
Core2 PO11 status P(bundled)
DC11 PO48 status P -- but only to Core2 - the interfaces to Core1 are suspended. (See attached configuration documents) None of the devices have any information in the logs. I run this same configuration in my central location, but we are running Nexus 7000's. With the 6500's, do I need to split the port channels on the 3750 to allow them to negotiate the etherchannel? If I split the portchannels, are there any concerns? Should I expect to see the etherchannel status as P (Bundled) or H (Hot-Standby)?

I have a new Cisco 2960 S series switch with a basic configuration that needs to be uplinked or daisy chained to a Cisco 3750 switch. I am not getting any connectivity to the network with either a straight through or crossover cable. the port remains in amber but a 'show interface' indicates that the interface is up. I can manage the switch with a PC patched into any port on the switch with a static IP address. Must be something very simple that I am missing. Outlined below is the configuration.

View 5 Replies View RelatedI own a Cisco 892W router. The router has 2 WAN ports and 8 switch ports. Now I know -
-WAN ports can create sub interfaces, assigne IPs, cannot be assigned to a VLAN - sounds very much like a routing port. (sh interface gives - Hardware is PQII_PRO_UEC)
-Switch ports are for VLAN assignment, trunking, IP assigment etc,. (sh interface gives Hardware is Fast Ethernet)
I know they are different but at the same time confuced what the difference are? I also know on some 3xxx series switchs you could say "no switchport" and translate a switch port to a layer 3 port. But on 892W you can't do this? Struggeling to understand the difference.

I manage a network with a ghost server, a 3750G, several outside access, and some vlans.This is a very simplify view of this network:
The ghost server is on all vlans connected to a trunk port on the 3750G which is used as a central switch and for basic routing.All equipements connected to vlans 1, 2 or 3 are on 2950 switchs themselves connected to the 3750G on dedicated access ports, each in there respective vlans.
All equipements connected to vlans 1, 2 or 3 have as gateway a vlan interface on the 3750. (10.0.x.3)All the vlan interfaces have route-maps applied on them to redirect traffic to their dedicated outside access.The route-maps match only traffic destinated to the outside.
Everthing is working well but the multicast.When I create a ghost session on the server, I can see computer connecting on it, but the multicast never start.If I use directed broadcast it works with good perfs, but the CPU processes of the 3750 go high because of the IP Input (Till 99%).If I remove the route map from the vlan interface which is on the ghosted network, the multicast works but with poor perfs.If I shutdown the vlan interface the multicast works well with good perfs.
It seems my problems are tied with the Vlan interfaces but I don't know why.

switch 1 provision ws-c3750g-24ts-1u
