We are getting log messages like
%EARL-DFC4-4-NF_USAGE: Current Netflow Table Utilization is 95%
%EARL-DFC4-4-NF_USAGE: Current Netflow Table Utilization is 99%
What this messages really means and how to get rid of these messages. We are using IOS version 12.2(33)SXJ in Catalyst 6500.
I tried to configure netflow without success.
Setup is the following.
Cisco Catalyst 6509 with Sup720-10GE IOS 12.2(33)SHX7. There are around 30 L3 vlans configured on the switch. I'm only interested for the traffic on one L3 vlan which is the connection to wan cloud.
I wanna see only the traffic that goes to and come from the wan. On other Catalyst where I have routed interfaces i successfully configured netflow. I read a lot in the forums and documentations but i didn't find the right one.
we have 6500 cisco switch as a backbone switch in universty. When ı want to look mac addres table , it does no show all mac address.ı mean if ı type ;show mac address-table there are not all mac address.

I'm trying to configure a egress netflow in a 6500 (VSS) with VS-S720-10G supervisor. I foud some old posts and understood that netflow wasn't supported on 6500 but i found a new document and it seems that netflow is supported in Supervisor Engine 2T:[URL] Does the netflow still not supported in VS-S720-10G? It's weird because the command is supported:
#sh run int vlan 4

We want to configure the "mac-address-table synchronize" command on our 6500 series switches to ensure that the CAM tables on our DFCs are in synch with the PFC on the supervisor modules. url...it is recommended that we disable the routed MAC purging with the mac-address-table aging-time 0 routed-mac global configuration command. What is a routed mac entry? Are there any issues with running that mac aging-time command?
We also plan to run this command "mac-address-table aging-time 14400" to keep our ARP and CAM tables on the same aging time to reduce unicast flooding on our network. Can we run this command with the "routed-mac" command above?
After a power outage our standby VSS switch has not recovered. The switch keeps cycling through its initialization and then powers off all modules.

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.
we have 2 catalyst 4507 Switches (Catalyst 4507-R running 15.1.2.release) configured in VRRP and vlans are distributed across both the switches.For few vlans core1 is master and for remaining vlans core2 is master.Both cores showing different CPU utilization.when we did our troubleshooting,we realized that the server vlan on core1 (Core1 is master for this vlan) is creating high utilization.when we switched this server vlan to core2 the core1 utilization came down and core2 utilization increased.we identified that server vlan is culprit in this issue. i would like to know weather any method is available in core switch wherein i can check which server in this vlan is contributing for this utilization.(To identify the server which contribute this utilization,we can actually shut 1 server each at time to see weather utilization is going down.with this kind of testing ideally we should be able to identify the server but this will disturb the server environment which we don't want in live environment)

1. We now have SupA & SupB in the chassis, due to some mistake we have same IOS version but different feature set on them, although we configured redundancy mode sso, in the "show redundancy" we see Operating Redundancy Mode = rpr due to Software mismat, we now need to fix them as same feature set image, if I use "copy sup-bootdisk0:/xxxx slavesup-bootdisk0:/xxx", then write memory, does this cause any service/network interuption?
Available system uptime = 1 year, 1 week, 4 days, 9 hours, 21 minutes
Switchovers system experienced = 2
Standby failures = 0
Last switchover reason = active unit removed
[code]....
2. We did a failover test with this status, found that if we triggered supervisor failover, all modules will reload thus the services if interupped. How about after we make the Operating Redundancy Mode as sso, will this behaviour shows again? Or a stateful failover will happens, then modules no need reload?
3. We are using OSPF as our L3 routing protocol, after reference to the configuration, nsf should be enabled, we want to ask in the OSPF-domain nsf should be configured in all OSPF-enabled router or only 6500 which have dual-sup?
4. We also found that the interfaces(3 * Gig & 2 * TenG) in Standby supervisor cannot be use even enabled & configured, is it because we are running rpr mode now or will be the same even change to sso? Before customer have some older supervisor in 6500 non-e chassis, and they can use the standby supervisor interfaces as traffic forwarding, they use rpr-plus mode before, how about in sso mode?
"How to display the EOBC error counters in the Catalyst 6500 series switches and a definition of the EOBC interface" document here on support forum stays that The Ethernet Out of Band Channel (EOBC) is a half duplex channel that services many functions, which include the Simple Network Management Protocol (SNMP) and the packets that are destined for the switch.
Previously i were thinking that EoBC used only for SCP and SLP protocol. In addition i found other article (but not on cisco site, heh) where stays that The Results bus is a control plane, while the C (EoBC) bus is more of an "admin plane", thus you will never see data packets (such as CDP, SNMP, etc.) going over the R or C bus.
So there is a big contradiction between those two statements. How to prove one of those and if first one right, what meaned under the packets that are destined for the switch in it? SCP and SLP or other traffic as well?
I am migrating services from SUP720-3B to VS-SUP2T-10G= and moving to a VSS configuration between a pair of Cat6506 distribution layer switches. I need to enable QoS on these switches, primarily to trust dscp and also to prioritise voice traffic. The autoqos feature works for some ports but does not work on port-channel interfaces and port-channel member interfaces. How can I apply the qos settings for these interfaces in line with what auto qos would normally provide. My line cards are as follows:
Civic_6506VSS#sho mod
Mod Ports Card Type Model Serial No.

The diagram below is the configuration we are looking to deploy, that way because we do not have VSS on the 6500 switches so we can not create only one Etherchannel to the 6500s.Our blades inserted on the UCS chassis have INTEL dual port cards, so they do not support full failover.
Questions I have are.
- Is this my best deployment choice?
- vPC highly depend on the management interface on the Nexus 5000 for the keep alive peer monitoring, so what is going to happen if the vPC brakes due to:
- one of the 6500 goes down
- STP?
- What is going to happend with the Etherchannels on the remaining 6500?
- the Management interface goes down for any other reason
- which one is going to be the primary NEXUS?
Below is the list of devices involved and the configuration for the Nexus 5000 and 65000.
