Cisco Switching/Routing :: ISSU Process On VSS 1440

Cisco Switching/Routing :: 3750v2 Any Limitations To OSPF Process

Jan 2, 2012

I've been reading the documentation for the new 3750v2 switch, and I'm wondering is the IPBase license supports FULL OSPF. The product sheet notes that it supports OSPF in the IPBase license, but then further down the page it notes that for advanced routing functions (EIGRP,OSPF) you need the IPServices license. Are there any limitations to the OSPF process on a 3750v2 with the IPBase license?

Cisco Switching/Routing :: 3750 - Enable EIGRP Process

Sep 23, 2012

I have a hub and spoke WAN that conisits of one core location with with a 6500 and nine other buildings using 4006 Catalyst that conenct back to the core via dual gig fiber. We are using EIGRP at each location as well as the core.   I was tesing something at one of our buildings decided to hang a 3750 off the 4006 and enable the same eigrp process on the 3750 that is enabled on the 4006 and 6500 (EIGRP 1).
1. All the routes that the 6500 knows about are advertised out to each of the nine locations.
2. The 4006's are all advertising thier directly conencted routes to the 6500.
Onto the location I was testing at:
The 4006 where I was testing at has four vlan interfaces enabled and they are in an UP/UP state. The ip routes from the 4006's directly conencted vlan interfaces propogate to the 6500 at our core location and the 6500 sucsefully propgates these learned routes to all the other 4006's.
This past Friday I configured a 3750x with two /22 vlan interfces and one physical gi port with an IP address and also configured on Ethernet port on the 4006 with an IP address in the same network block as the 3750x gi interface (a /30 netowrk block). I saw both interfaces come up and EIGRP sucesfully established a neighbor adjecency between the 3750x and the 4006.
I noticed that the 3750 advertised out all of it's directly conencted routes to the 4006 and the 4006 advertised it's directly conencted routes to the 3750. However, the 4006 did not advertise any of the routes it had learned from the 3750x to the 6500 and nor did the 4006 advertise any of the routes it had learned from the 6500 to the 4006.  My suspicion is that the "eigrp stub connected summary" statement is enabled on both the 4006 and 3750 thus prevenintg them form advertising out any routes other than thier directly conencted routes.  Can any of you verify that I'm either correct or inccorect about this?
here are the eigrp statemnets from the 6500 and 4006:

Cisco Switching/Routing :: 2921 Process Of Switching Infrastructure Of Firewalls / VPNs

Jul 4, 2012

We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco.  We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages.  Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication.  In the past, because they are logged into the domain internally, the website authenticates and loads.  After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

Cisco Switching/Routing :: 6500 / Nexus OSPF Process Limit?

Jan 11, 2012

We are cutting over from 6500 IOS to Nexus 7000 and have hit "Maximum ospf feature instance limit reached." as we configured up the 7 existing ospf processes - the limit is 4. These existing processes are for various vrf contexts we have. I see you can run multiple vrf contexts under one process - but how does that work in a mixed environment where the ospf neighbours are still ios 6500s? They still expect to see different ospf process id per vrf.

Cisco Switching/Routing :: How To Configure 6506 Or 2960G To Process Multicast Traffic

Aug 8, 2012

Multicasting.  The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10.  I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch.  On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10.  The 2960G switch has a workstation connected to it that needs to receive the multicasts.  How do I configure the 6506 and/or the 2960G to process the multicast traffic?

Cisco Switching/Routing :: 6500 How Long Conversion Process Takes Place

Dec 5, 2012

We will be converting two 6500s to VSS. Each chassis has a Sup2T module, fwsm, 6908-10G blade, wism1 blades and two or three 6748-SFP blades. I was wondering how long the conversion process takes?  If I remember correctly at the 2012 networkers lab it took maybe 10 minutes while using Sup720s.  The instructor mentioned that with Sup2Ts it would convert a lot faster.

Cisco Switching/Routing :: 3570 / Multi-process OSPF Redistribution And Failover?

Feb 7, 2013

I have two ospf processes running on a single 3570 edge router that has a dedicated transport circuit back to our network core. We are adding an additional "transport" only circuit into a new location that is also apart of the second ospf process backbone which will connect back to our core. There will also be a 3750 for this new circuit termination. Currently we are only redistributing ospf process 2 into ospf process 1 (1 = core backbone).

#router ospf 1
#redistribute ospf 2 subnet
We have no need to have ospf process 1 redistributed into the process 2 tables. That being said, when we add an additional transport ciruit, or path back to our core backbone, will this configuration present any issues with the redistribution process and failover.

Cisco Switching/Routing :: Small Business 300 Series / Another Copy Process Is Active Message

Nov 2, 2010

i have major problem with two new Small Business 300 Series switches.Everytime i try to save the running config i get a GUI error message: "Another copy process is active, please try again later."It's also not possible to re-flash the firmware because the GUI stops responding.I have also tried to do this via console access and this produces a "the copy utility is occupied by another user" error message.-> so this is not a browser based problem.My first thought was that the switch (SG 300-28) is faulty so i unpacked the next new one (SF 300)and got the same error messages!Then i had a 2 hour webex support session with the Cisco Small Business Support and they did not found a reason for this behavior.Both switches are working normally, you can configure them, but after a reboot they are back to factory default again There is no possibilty for copy running config to startup config and it's also not possible to flash the firmware.(Web GUI & Console). tell me if this is a fundamental problem of the 300 Series?

Cisco Switching/Routing :: WS-C3750X-24S / Continuous High Processor Utilization Involving Hl3mm Process

Apr 3, 2012

We are running a stack of 2 WS-C3750X-24S-E's with IOS version 12.2(58)SE2 and we are seeing continuous high processor utilization involving the hl3mm process.  The stack is configured for PIM Sparse mode, with 2 upstream Nexus 5596'es acting as both RP candidates and as BSRs.  The hl3mm process generally runs at about 19% but can spike up into the 60% range.Symptoms on the 3750X are spiking latency and sluggish CLI perfformance.  I thought at first that we might be running into SDM limits, but the "show platform tcam utilization" show that we are far under the limits of the default SDM template.  Performing the "show ip pim (vrf name) bsr-router" command freezes the system and takes 20-30 seconds to return results.  Similiarly configured WS-C3750G-12S running 12.2(55)SE3 does not exhibit these same issues.

Cisco WAN :: 2801 High CPU - NAT Process Or CEF Switching?

May 17, 2011

I have in my router 2801, one link with 20 MB WAN Connection, and it is presenting high cpu utilization with 97% Interrupt Errors when start one download.
I exchanged it to another router the 2811 and it presented the same results. I read the cisco document about Router Performance.
And it speaks about the 2801 supports 46 Mbps using CEF/Fast Switching and 1.5Mbps using only Process Switching, and 2811 supports 61.44 CEF and 1.5Mbps Process Switching.
I need to know if the NAT Process is process switching or CEF Switching. Because if it was process switching the router is working in the max capacity and i will need to exchange the hardware to a better hardware.
