Cisco Switching/Routing :: 6500 Clarification For Using Mac-address-table Synchronize Command

Jul 12, 2010

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. 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?

Cisco Application :: 6509-E SUP720 And SLB Limitations?

Mar 21, 2012

We are looking into replacing our current Windows NLB configuration with a SLB solution as NLB creates some nasty multicast traffic.
We are currently curious about the limitations for running SLB without a dedicated ACE Module, will it handle line-rate speed (1 and 10 gbit) with SLB?
Does VSS introduce any limitations for SLB? Any other pitfalls/limitations we should be aware of?
Hardware info: 2x WS-C6509-E in VSS with VS-S720-10G (VS-F6K-PFC3C) running s72033-ipservicesk9_wan-mz.122-33.SXI7

Cisco WAN :: Cat 6500 IOS Upgrade - Installing Secondary SUP720 In 6509-E

Nov 21, 2011

I will be installing a secondary SUP720 in a 6509-E and will be upgrading the IOS on the existing SUP which is on  122-18.SXF6. I've read that this release has passed End of Critical Maintenance earlier this you. I thinking of upgrading the IOS to 12.2.33-SXJ1(ED) or 12.2.33-SXI8(ED) (possible more stable), but i'm not sure if i need any step upgrades from the current version. The SUP meets the required hardware specs and I will also be upgrading the ROMMON to 12.2(17r)SX7 first.
I have alot of experience upgrading IOS on routers and switches, but i just need to now if there are any gotchas that i need to know for the upgrade on the SUP.
The other issue is i don't believe the current IOS has been installed, are there any issue running on an IOS not installed. Patching is not available since the system is not running from an installed image. To install please use the "install file" command.

Cisco Wireless :: 6500 - Why WiSM2 Not Recommended In SUP720 Slots

Jun 27, 2012

I have a situation where a customer doesn't have the required power units installed in their 6500 for me to provision a WiSM2.They use a VSS pair with a single Sup720 in each. They have no intention of adding a second Sup to each chassis.

I need to justify why they can't use slot 6 (which has power reserved) if I am to get them to upgrade the PSU's. The documentation I've found says it is supported but not recommended.

Cisco :: Configure Netflow Catalyst 6500 With SUP720-10GE

Jun 5, 2012

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.

Cisco Switching/Routing :: 6500 - Upgrade From SUP720 To SUP2T With New Chassis?

Apr 28, 2013

We recently purchased 2 Cisco 6500 series switches (with Sup 2T). These switches will be replacing our old 2 6500 series switches (with Sup 720).
We have 70 vlans and 90+ closet switches (2900) connecting the core switches We have 2 WLC connected to the core switch. We also have a 1 x 1 connection to a VSS switch which in turn connects to our Server Co-Location data center utilizing IPSec & GRE tunnel to connect to our Server Co-Location data center.
Our routing protocol is EIGRP. Our VTP domain at Server Co-Location is separate from our location “A” campus. I was wondering what is the best way to migrate our Core switches at location “A” campus.
The requirement is we would like to replace these switches with minimum downtime.

Cisco Switching/Routing :: Web-sense Security Gateways Connected To 2x 6500 SUP720

Dec 8, 2011

I have 2x v10000 Websense Security Gateways that are connected to 2x 6500 SUP720. When I turn on cluster management function between Websense appliance, they speak to each other only if they are connected in the same 6500. When they are connected one in every 6500 cluster management does not work. They are connected on the same physical vlan. Do I need multicast to be configured in the 6500 switches?

Cisco WAN :: 6500 Processor Memory And BGP / RIB Table

Jan 23, 2013

We have a couple of 6500 series switches and have 3 BGP peerings to each. The 6500 series switches are loaded with WS-SUP720-3B Supervisor Engine. I believe there is a limit to the number of IPv4 routes WS-SUP720-3B supports(256,000). We also have "soft-reconfiguration inbound" configured on the BGP peerings. Thus when I do a "show ip bgp A.B.C.D" it displays three routes from 3 BGP peers and it displays an additional 3 "received-only routes" which I think is due to the "soft-reconfiguration inbound" configuration. We currently filter inbound routes from the BGP peers to be between /0 and /27
We are now looking to add another 2 BGP peerings. I am not too sure if the WS-SUP720-3B will be able to handle all the BGP routes. Is this limit of 256,000 IPv4 routes due to Processor memory limitation or is it software related? Would removing the "soft-reconfiguration inbound" save me some memory ?

Cisco Firewall :: ASA 5510 - Data Center Move / IP Address Change

Nov 4, 2012

We will be moving to a new data center in the very near future and with them our WAN IP addresses will be changing. Any best course of action for changing the IP addresses throughout the firewall configuration? Would it be possible/suggested to export the running-config, make the neccessary changes, then import the config? I am familiar with the ASA 5510 only so far as changes are required. It is not something I work with on a regular basis.

Cisco VPN :: Does ASA5505 EzVPN Support Reactive Primary Vpn Server Feature

Nov 24, 2011

i am going to configure asa5505 as the azvpn client . and configre primay and secondary vpn server in the list.i find some feature that is support by ios ROUTER  ezvpn, not sure it will be support on ASA ezVPN???
will the ezvpn   fall back to the primary vpn server , if primary back on line,  on ASA? The Reactivate Primary Peer feature allows a default primary peer to be defined. The default primary peer (a server) is one that is considered better than other peers for reasons such as lower cost, shorter distance, or more bandwidth. With this feature configured, if Easy VPN fails over during Phase 1 SA negotiations from the primary peer to the next peer in its backup list, and if the primary peer is again available, the connections with the backup peer are torn down and the connection is again made with the primary peer.

Cisco Switching/Routing :: Location Of FIB And Adjacency Table In Both 6500 Series And Fixed Ports Switches

Apr 28, 2012

I 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.

Cisco :: Getting Mac-address-table Through SNMP On 1811

Jan 26, 2010

trying to fetch the equivalent of the mac-address-table on a 1811 with SNMP. I want a mapping between active MACs to a port ifIndex (not a VLAN interface ifIndex).
- I've snmpwalked every MIBs on this device (including all the proprietary MIBs supported by the IOS)

- I've upgraded to latest IOS from the 12.4(24)T series and also tried latest from 12.4(15)T series

- I am aware of the community index (@ sign in read-only community to split per vlan)

- I've exhausted all my google skills
On 29xx, 35xx, we obtain that information using the BRIDGE-MIB, community indexing and the following OID: (dot1dTpFdbPort)
# snmpwalk -v 2c -c public@1
SNMPv2-SMI::mib- = INTEGER: 24
SNMPv2-SMI::mib- = INTEGER: 12
SNMPv2-SMI::mib- = INTEGER: 11
