VLAN Interface Utilization

Hello,
I have Cisco Works LMS version 3.0.1 that manages the Core switch and the access layer switches. Can I use Cisco Works LMS to measure the throughput of the traffic passing from/to a specific interface VLAN? If yes, do I need Cisco LMS only or I have to have Health and Utilization Monitor (HUM) installed?
Kind Regards
Mohamed

If the layer 3 SVI was showing 100% that means it had a lot of traffic that was being layer 3 processed switched instead of hardware switched . Normally most traffic is hardware switched within the ASICS and never even gets passed up to that layer . What would cause this I'm not sure .

High VLAN Interface utilization (6500/sup720)

Can anyone tell me why a VLAN interface would show 100% utilization for a givin VLAN? This is a sup720 we're talking about.
I understand that the bandwidth of a virtual interface is 1Gig but I thought this was more related to routing metric.
Users were actually seeing performance issues until we changed how the servers on this particular interface were replicating. Once we did this the VLAN interface utilization went down and performance went up.
It doesn't make sense to me that the VLAN interface would limit the actual throughput of the various ports that are mapped to it. Throughput should be related to the switch module 61xx, 65xx, 67xx and how it interfaces to the backplan and the backplan speed itself.
Any insights would be helpful......

Interface VLAN Bandwidth Utilization Reporting

I am currently evaluating a few products for Network Management and Monitoring. The question i have is, how is % utilization calculated for a virtual interface? Some tools have reported that one of our interface vlans is at 320% utilization. Obviously, this is not accurate. If anyone can give me advice on how to accurately report interface utilization percentage on a virtual interface, I would appreciate it.

No, changing the vlan speed will not influence the physical interface's speed.
So, no need for that.

EIGRP IPv6 and VLAN interfaces

We've found that we have to set static link local IPs when two routers might peer over multiple VLAN interfaces.
The issue is that the routers, 6500s with sup720s, utilize the same autoconfig'd link local address on each VLAN interface.   EIGRP IPv6 refuses to peer with the other router on multple VLANs when the link local are the same.
Anyone else encounter this?   Did we miss a config option that would force unique link locals on different VLANs interfaces?
Because of this issue, we've made it our best practice to configure static link local for all inter-router transits.

HI Gary,
I had a setup with SU720 on 2 7600s and I am able to enable the neighborship without any issues. I didnt configure static link local as below,
Ryanair#show ipv6 int vlan 500 | inc FE
IPv6 is enabled, link-local address is FE80::21C:B0FF:FEB5:6D00
Ryanair#sho ipv6 int vlan 501 | inc FE
IPv6 is enabled, link-local address is FE80::21C:B0FF:FEB5:6D00
Ryanair#show ipv6 eigrp nei

LMS 4.2.3 Query on Interface utilization report

Hi All,
Interface Utilization report displays the interface utilization data for each device polled for the Interface Utilization
template. The information is presented using the percentage specifier.
For eg its displayed % (Rx Max%,Rx Avg%,RxMin%,
Tx Max%,Tx Avg%,TxMin%)
I wants report should have the data(interface utilization In Bytes of data)
Can we display the data instead of the percentage?? is it possible ???

Hi Channa,
log into dbreader using the following::
http://servername : 1741/dbreader/dbreader.html
or
https:// servername : 443/dbreader/dbreader.html
user Id is DBA
Database Name is upm

1. Here is the query to get the pollerwise managed MIBObjects:
"select count (*), PollerName from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId = b.PollerId and b.Poller_State NOT IN (1) Group by b.PollerName;"
2. Here is the query to get the total mibobject count for the active pollers
“select count (*) from Poller_Details_Table a,Poller_Definition_Table b where a.PollerId =

LMS 4.2 specific interface utilization report

Hi,
is there a way to create a interface utilization report only for a specific port? Like switch1->interface fa0/10
Right now i can only choose all ports from a device?
Thank you.
Chris

So, the new weekly report does not show the high Utilizations anymore, but there is a new problem:
In the "Report Details", there are 7 devices and 126 interfaces, but in the "Interface Utilization Summary", there are only 49 Interfaces.
I have added a screenshot, so that you can see, what I mean.

Cisco PI 2.1 can't display monitoring interface utilization result

Hi Experts,
Our company have a Cisco PI 2.1 system, I want to monitoring some router's interface utilization.
I followed cisco prime training course to set up some config in cisco PI, but it's seemed to be not effective.
There's no result can be displayed in PI, I have no idea the root cause, can anyone help me with it?
The config detail please refer to attachment.
Thanks in advance,

It's a VM.
I chose the Express-Plus profile even though I could technically have used the Express profile for what they're managing. I always try to err on the side of more resources when building a management system. Getting a customer to adapt their workflow to properly leverage a NMS is hard enough without it also being a drag to use due to system sluggishness.
We're also running it on a nice new shiny data center - UCS B240 series blade with fast storage on Netapp SAS disks and connected directly to the 7010 core (via the Fabric Interconnect of course).

Could I use "vlan interface" as a tunnel source of DMVPN ?

I have a router R2811 with a 9 port FE Switch module(HWIC-D-9ESW).
Could I use vlan interface as a tunnel source when configuring DMVPN ?
The vlan ports is on the 9 port FE Switch module.
Because it's used now in production,I can't try it.

Hello.
I think there is no restriction on software routers like 2811.
PS: using loopback could be a better idea.

Netflow on 6509 in Native Mode from Vlan Interface

I'm trying to get a 6509-E, running Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICES_WAN-M), Version 12.
2(33)SXI9, RELEASE SOFTWARE (fc2), to send netflow traffic from a vlan interface to a Solarwinds server.
The server is not seeing all the vlan traffic, but does see all the traffic on the layer 2 ports (not netflow).
I've seen that a command, ip flow ingress layer2-switched vlan, needs to be enabled, but the OS I have does not support that command.
Or could it be that MLS is not configured except for a couple commands:
mls netflow interface
mls cef error action reset
netflow setup:
Flow export v5 is enabled for main cache
Export source and destination details :
VRF ID : Default
    Source(1)       10.31.101.1 (Vlan52)
    Destination(1) 10.30.2.196 (2055)
Version 5 flow records
14927339 flows exported in 615072 udp datagrams
0 flows failed due to lack of export packet
0 export packets were sent up to process level
0 export packets were dropped due to no fib
0 export packets were dropped due to adjacency issues
0 export packets were dropped due to fragmentation failures
0 export packets were dropped due to encapsulation fixup failures
0 export packets were dropped enqueuing for the RP
0 export packets were dropped due to IPC rate limiting
0 export packets were dropped due to Card not being able to export
interface:
interface Vlan52
description AN.VDI.stu
ip address 10.31.101.1 255.255.255.0
ip helper-address 10.31.149.200
no ip redirects
ip flow ingress
ip flow egress
ip pim neighbor-filter 98
ip pim sparse-dense-mode
ip cgmp

Enabling MLS was the fix.
mls netflow interface
mls flow ip interface-full
mls nde sender version 5
mls cef error action reset

VLAN Interface Command

Ok, I thought I had the reason for the VLAN interface command down. I thought it was either used for switch management or routing between VLANS? However, now I realized that some communication wont work with out this command which doesnt make sense. If I have a VLAN, then the switch will only switch packets to ports on the same VLAN. The only way, communication would work between VLANS is if I either enabled routing between VLANs with the VLAN Interface command, connected the switch to another multi-layer switch that did do routing between VLANS, or connected the switch to a router which routed between the VLANs.
However, I just got this new 3550 switch in, configured the correct ports with the assigned VLANs, and the only way my cisco ip phone would work is if the VLAN Interface for my voice-ip VLAN was configured. The 3550 is connected to a 4507. Now, can someone tell my why this is? You shouldnt have to configure the VLAN Interface, right?(unless I wanted to route between VLANs, which could be done by the 4507)

Sounds to me like you either dont have the dot1q trunk interface between your 4506 and 3550 working properly, or your 3550 is running the enhanced image which allows routing.
It would be nice to see your config on both the 3550 and the 4500 to determine the reason. Just a stab at how it should be configured is that on your 4506, you have it running VTP server or transparent with the defined Data and Voice Vlan's. You have a port configured for trunking (which connects to the 3550). On your 3550, you have configured it as a vtp client or transparent and have verified that it has received (or if transparent VTP you have configured) the appropriate VLAN's. You than specified "interface VLAN #" or whatever number for switch management and configured the port that connects to the 4500 as a trunk. Your port connected to the port has the auxillary or voice vlan configured. If this is how your equipment is configured and it still does not work, than look for the line "ip routing" in your 3550 and negate it with "no ip routing".
If still no worky worky, post your config.
Cheers,

Customizing performance threshold for interface utilization in LMS 4.0

Am running LMS 4.0, i want to customize performance threshold for interface utilization from the default 40% to x%, please help.

Based on your other post, I think you're talking about Device Fault management. You can go to Monitor > Fault Settings > Setup > Threshold Settings, and select the DFM > System Defined Groups > Interface and the interface type you want, then edit the thresholds for this group. Change the default utilization threshold from 40% to your desired value. Save your changes, then go to Monitor > Fault Settings > Setup > Apple Changes to apply them.

ACE - Query VLAN Interfaces Status

Hi,
I am wondering what the status of the query vlan interface means in the command 'show ft peer detail':
Query Vlan IF State : UP, Manual validation - please ping peer
I am pretty sure that I did not see this status when I configured query vlan last time. Current version is A2(2.3).
Unfortunately this status does not seem to be documented anywhere on CCO.
I appreciate any help!
Thanks,
Daniel

Hi Daniel,
The FT Query VLAN interface is an optional, yet very good, feature to be used when using redundant ACE modules or appliances. Without it, if the FT VLAN was to go down, the standby ACE will no longer receive FT heartbeats from the active ACE and therefore take the active role. However, if the active ACE is still running fine in the active role, then you don't want the standby ACE to take over as active because that will put them into an active/active scenario, which may lead to connectivity issues.
This is where the FT Query VLAN interface comes in. If the FT VLAN goes down, the standby ACE will notice this, but before taking the active role, it will ping it's peer IP address configured on the interface that is designated as the FT Query VLAN. If the ping is successful, then it will stay in the standby role, thereby saving you some headaches.
The status that you are seeing is the ACE's way of telling you that the interface is UP, but if you want to know if it can successfully ping the peer IP address, then you would have to manually ping the peer IP address from the CLI. The ACE does not periodically check the ping connectivity through any automatic mechanism. The automatic mechanism is only triggered by the FT VLAN going down.
Does this help?

WLC - 4402/4 - Vlan Interface Addressing

I currently have 7 WLCs with the same Vlan interfaces defined across all 7 controllers. Does anyone know the best practice for addressing these interfaces on each of the WLCs. I currently have each unique Vlan interface assigned with the same IP address across all 7 WLCs. This is working. Should I leave it this way or should I assign each controller with a different address for the Vlan interface?

The controllers, assuming you have it configured as such, act as dhcp relay agents. Presumably, if the router got the wrong mac address in its arp entry, the dhcp message would be lost.
Clients could have taken a while before getting a dhcp addr (race condition for router arp entry) and not been able to work if dhcp was required.
That said, I've seen the controllers work with the dhcp server set to 255.255.255.255 so the ip helper addresses on the routers would pick up the requests.

VLAN interface on ME2600X

I'm trying to configure a VLan interface on my ME2600X (for inband management), but the switch won't accept the command.
What am I missing? I need a way to combine layer-2 services and a management vlan on the same dot1q trunk into the ME2600X.
Geir Jensen

Hello Geir,
You can use service instances e.g.:
interface GigabitEthernet0/3
switchport trunk allowed vlan none
switchport mode trunk
dampening
mtu 9100
load-interval 30
media-type rj45
service instance 5 ethernet
description Management VLAN
encapsulation dot1q 5
rewrite ingress tag pop 1 symmetric
bridge-domain 5 – this will pop up message:
Bridge-domain 5 created
VLAN 5 does not exist, creating vlan
interface Vlan5
description Management VLAN
ip address 10.0.0.1 255.255.255.0
ip access-group MNGT-ACL in

VPLS with IP in the vlan interface

I have this config in a Cat6500:
l2 vfi XXX manual
vpn id XXX
neighbor 1.1.1.1
interface vlan XXX
ip addrr 2.2.2.2
xconnect vfi XXX
With this config I can't reach from 6500 other equipments on this vlan with vpls.
It is ok to setup an ip address in a VLAN interface even if the interface have VPLS "xconnect" configuration?

Hi Guys,
I would like to put my idea only but i do't know if it is correct or not.
but if we defice any ip address on the interface than this will help us to improve anything but will appear in the routing table of PE router and it could be a part of it's routing and MPLS which is not required.
secondly we are trying to emulate layer2 briedge accross the VPLS backbone not the Layer 3 switch domain. than it could be possible that you configure routing accross the backbone but there is no such kind of mechanism to enable routing.
please rate if it helps.
