Hi ,
Prime infrastructure uses MIB to collect the Mac address of the clients; this MIB collects
the information per vlan.
So we need to configure SNMP context for all vlans to view the wired client.
Try configure SNMP context on devices , then delete and re-add the device and check the issue.
For e.g:
snmp-server group gcobergroup v3 auth context vlan-1
snmp-server group gcobergroup v3 auth context vlan-71

Cisco prime 2.1 not showing wired clients connected to Cisco 3850 switches

Hello All,
I have around 80 Cisco 3850 switches at a customer network and they are using prime infrastructure 2.1.2 to manage these devices. Most of the features are working fine except that the prime does not show the wired clients connected to the switches. The wireless clients are shown properly but not the wired clients. Their core switches are nexus 7k. The SNMP configuration on the switches is as follows.
snmp-server group xxxx v3 priv write xxxx-VIEW-WR
snmp-server view xxx-VIEW-WR mib-2 included
snmp-server trap-source Vlan100
snmp-server host x.x.x.x version 3 priv testuser
Please help me to resolve this issue.
Shabeeb

I managed to get the end hosts connected in 3850 switches with the use of snmp context command. But now the issue is that prime is showing only the mac address of the device , not the IP address.
Is there anyway to resolve this issue?

Cisco Prime Infrastructure 2.1 Not generating reports

Dears,
I am new to Cisco Prime. I installed Cisco Prime Infrastructure 2.1 for 60-days evaluation and i added routers, switches and APs. I configured SNMP community and telnet credentials. I can see clients on Dashboard, but when i go to reports and generate them for last hour, it displays "None Detected".
Please advise.

Programmatic access to PI's data is via the REST API.
Check the help menu on your PI server to see documentation regarding the supported tables and fields that can be queried via that method.

Cisco Prime Infrastructure 2.0 not showing alerts from switch

Hello,
I have a prime infrastructure 2.0 running at a customer place and the customer now complains that he is not receiving link up/down messages from the switch. When i checked I have seen that if I shut down a port in the switch the prime identifies after a long time, but its not generating an alarm still. How can I fine tune the prime to fix this issue. Please help on this.
Thanks in advance

Hi,
Same problem here.
I am using Cisco Prime Infrastructure 2.0 (evaluation version for 60 days). I want to deploy port monitoring for my trunk ports between switches and some other important ports e.g. servers. Basically I want to get alarms when these ports are down, there are errors on ports and etc.
So in Design>Port Grouping I created User Defined group with important ports. In Deploy>Monitoring Deployment I selected Interface Health (default)>Deploy selected Port Groups and when selected port group I created.
Now the rule shows Deployed: Yes and Status: Active. After that I just pulled out one port which was in monitored group, waited 5min as it is set in Interface Health (default) template, and nothing happened, and worse, alarms started to show up of other ports where regular users are connected (computers was turned off), which I do not want to see at all. I tried redeploy template, I even created my own template but still no desired result.
Any suggestions how to make port monitoring work?

WRT54G v6 client table not showing wired clients

I have a WRT54G v6 using the lastest firmware. Is there any 3rd party software that can display what clients I have on my network? The reason I'm asking is because my router will only show the wireless clients and not the ones connected on the wired side. Other than that everything works fine.

I have similar problem. DHCP client table shows only wireless laptops using dynamic ip address. All my wired destop (dynamic ip), and other static ip devices both wired or wireless do not show up in DHCP client table. Any idea? I have v8.

Cisco Prime Infrastructure 2.1 not send email alert when link down

Hello everyone
I use PI to monitor 1 switch and 1 firewall . When a link up/down on switch , PI immediately sends an email alert .
But when a link up/down on FW , PI not send any email alert . PI knows link up/down on a FW is a critical alarm ( it's show up on "Alarm Browser") , but not send email.
I enable all SNMP trap on FW , i tested that event on SolarWinds and it immediately sends an email alert . So there is no problem about FW config

Causes of Errdisable
This feature was first implemented to handle special collision situations in which the switch detected excessive or late collisions on a port. Excessive collisions occur when a frame is dropped because the switch encounters 16 collisions in a row. Late collisions occur after every device on the wire should have recognized that the wire was in use. Possible causes of these types of errors include:
A cable that is out of specification (either too long, the wrong type, or defective)
A bad network interface card (NIC) card (with physical problems or driver problems)
A port duplex misconfiguration
A port duplex misconfiguration is a common cause of the errors because of failures to negotiate the speed and duplex properly between two directly connected devices (for example, a NIC that connects to a switch). Only half-duplex connections should ever have collisions in a LAN. Because of the carrier sense multiple access (CSMA) nature of Ethernet, collisions are normal for half duplex, as long as the collisions do not exceed a small percentage of traffic.
There are various reasons for the interface to go into errdisable. The reason can be:
Duplex mismatch
Port channel misconfiguration
BPDU guard violation
UniDirectional Link Detection (UDLD) condition
Late-collision detection
Link-flap detection
Security violation
Port Aggregation Protocol (PAgP) flap
Layer 2 Tunneling Protocol (L2TP) guard
DHCP snooping rate-limit
Incorrect GBIC / Small Form-Factor Pluggable (SFP) module or cable
Address Resolution Protocol (ARP) inspection
Inline power
Note: Error-disable detection is enabled for all of these reasons by default. In order to disable error-disable detection, use the no errdisable detect cause command. The show errdisable detect command displays the error-disable detection status.

ISE integration with Prime Infrastructure,

Hi Team,
I would like to know what are the advantages and Disadvantages of the ISE integration with Prime Infrastructre.Also how the LAN, wifi, and identity management part (guest access etc) will work together.
Cheers!!!
Minakshi

Prime Infrastructure manages the wired and the wireless clients in the network. When Cisco ISE is used as a RADIUS server to authenticate clients, Prime Infrastructure collects additional information about these clients from Cisco ISE and provides all client relevant information to Prime Infrastructure to be visible in a single console.
When posture profiling is enforced in the network, Prime Infrastructure talks to Cisco ISE to get the posture data for the clients and displays it along with other client attributes. When Cisco ISE is used to profile the clients or an endpoint in the network, Prime Infrastructure collects the profiled data to determine what type of client it is, whether it is an iPhone, iPad, an Android device, or any other device.
Cisco ISE is assisting Prime Infrastructure to monitor and troubleshoot client information, and displays all the relevant information for a client in a single console.

New installation of Cisco prime Infrastructure 1.2

Hi,
We installed Cisco prime infrastructure 1.2 and discovered our entire LAN swtiches and core L3 Switches.
In Cisco Prime, we are getting information related to Device and IOS. But intreface ulitilzation information are not avilable.
we used SNMPv2 RW string and and SSH username for discovery.
How to get the interface ulitization data ?

Under Administration > System Settings, then select Monitoring Settings.
i checked the two options
Auto monitoring
Enable deduplication
But after refresh it is show uncheck, i tried in Google Chrome and Firefox.
Is this cause the issue of not polling interface netflow???

Migrate Guest Users from Prime Infrastructure 2.1 to ISE

I have just installed a new Prime Infrastructure Server and have discovered our list of guest user accounts from the discovered Controllers. We are implementing ISE 1.3 and would like to move all the guest user accounts from Prime to ISE without doing it manually. Is there a way to either export or pull the guest users from Prime or the WLC and import them to ISE?
I would be very interested to find out if this can be done.
Cheers,
Tom

Can WLC's built-in DHCP provide IP addresses for wired client?

Hi,
We've got a WLC running on 7.0.98.0. It's providing IP addresses for the Guest Wireless users. Now we'd like to put a couple of wired workstations for those customers who don't bring laptops. I'm wondering if I put these workstations on the same guest wireless vlan, they can still get IPs from the WLC. If not, I have set static IPs on these workstations.
Thanks in advance.
Robert

Rob:
The answer is simply "No". WLC can not provide wired clients on same wireless VLAN with IP addresses if the DHCP is configured on WLC.
The case metnioned by fbarboza above is a "very" special configuraiton on WLANs where the WLC is configured to take care of some wired clients and it needs you to have two WLCs (The featured is called wired guest).This special case does not apply at your situation.
With your situation my answer above applies.
Note A internal DHCP server pool will only serve the wireless clients of that controller, not clients of other controllers. Also, internal DHCP server can only serve wireless clients and not wired clients.

Cisco Prime Infrastructure automatic configuration Archieve

Hi all,
I installed Cisco Prime Infrastructure and I note that it make configuration archieving for all devices on it with different date.
I need to know based on what it selects the date on which it take the archieving of configuration (note that it takes archieving of all boxes on different dates) ??
thanks,
Best Regards.

Hi Mohamed,
The configuration archive will run every day, however if there is no change between today's configuration and the previous check, there is no point in archiving it again.

Cisco Prime Infrastructure 2.2 clients and users IPs not detected

Hi all,
I have cisco PI2.2 and discovered all the network and i notified that there are some clients' IPs (Servers or PCs or Laptops or ....) not detected.
please advice what may be the issue ?

Hi,
does anyone happen to know if that problem is fixed? My currently setup looks like this:
1. Cisco Prime Infrastructure 2.1 with updated device pack.
2. Assurance license
3. ASA5510 which has enabled netflow. Netflow is being sent to Cisco Prime 2.1
I do receive netflow raw data within Cisco Prime 2.1 but any graphical display of netflow data is not working. Does anybody has an idea where the problem is? Could it be that the graphical data is only displayed when sending netflow 1, netflow 5 or netflow 7?
regards

Cisco Prime 2.0 - Nexus clients not discover

Dear all,
I've installed a Cisco Prime infrastructure 2.0 and it's working perfectly except for Nexus 7k : I canot see the wired client connected (useful for traking) while it's working fine on many other devices. The devices are managed with an inventoy collection completed (No data vailable in Device Details/ clients / current associated wired clients).
any idea ?
regards,
vincent.

Hi Vincent,
I have this problem too. I found this related information about supporting "clients and Users" for Nexus in PI2.x/LMS4.2.4.:
Cisco Prime LMS 4.2.4 - User Tracking for N5K: https://supportforums.cisco.com/discussion/12155236/cisco-prime-user-tracking-n5k, User Tracking require the SNMP-BRIDGE-MIB on the target device(s). That was introduced in NX-OS 6.02 on the Nexus 5000 platform.
LMS 42 user tracking: https://supportforums.cisco.com/discussion/11605281/lms-42-user-tracking.
Nexus 7k and 5K in LMS 3.2.1. “When adding the Nexus devices to DCR, provide the “netadmin SNMP RO credential”. When other SNMP RO credential is provided, user tracking will not collect end host data. The Nexus device should be running NXOS 5.1(1), 5.1(3) or later. 5.1(2) is not supported.
Configure the device to map community with context using the below command: snmp-server context vrf, snmp-server mib community-map context
Please let us know what the progress is of the TAC case. I'm very interested.
Kind Regards

Cisco prime infrastructure not detect IP address of clients

hi all,
I have Cisco Prime infrastructure 1.2 and when move to monitor >> clients tab it lists me all the clients in my network but their IP address list estates "not detected" ?
please any advice?
I appreciate your kindly support.

Just an update that while this appears to have worked fairly well (as far as Cisco Management Planes go), there was one small 'gotcha' I've noticed so far:
After the services came back up, the entries for our RADIUS servers did not function. No, not because I didn't update the clients address record on the RADIUS server itself, but because the RADIUS server record(s) within CPI have a field called 'Local Interface IP' that still reflects the previous IP assigned to CPI. A quick edit/save with the new interface fixes up the issue however.
Cheers!

Prime Infrastructure 2.2- problems: Wired Detailed Device Inventory report not running / Cisco 5500 WLCs no listed in subgroup

New installation of Prime Infrastructure 2.2.0 (PI-VA-2.2.0.0.158.ova)

PI 2.2.1 Maintenance Release (installed,ncs stopped,rebooted)
Prime Infrastrucutre 2.2 Device Pack 3 (installed,ncs stopped,rebooted)
Licences installed (ncs stopped,rebooted)
Added all devices via Bulk Import (Inventory>Device Management>Network Devices)
Problem 1:
The Cisco 5500 WLCs are not listed in Inventory>Device Management>Network Devices (see screen shot) but listed under "All Devices"!
The Cisco 4400 WLCs and the 8500 WLCs are listed within their subgroup.
Devices are in "Managed State"
Problem 2: fixed! (Browser issue)
Problem 3:
Unable to run "Wired Detailed Device Inventory" report because I get the error message: Failed to run report: Unable to retrieve data for: Chassis Information (if Chassis Information is selected, if System Information is selected I get the error message with ...retrieve data for:System Information)
All devices do have an "Admin Status = Managed" and the Last Inventory Collections Status = Completed.
Has anyone the same issues or a tip for me?
Another topic, the "User Defined Fileds" are not exported when with running a "Device Export" (Inventory > Device Management > Network Devices). ;-(

Hallo Bastian,
I think you still have browser issue, Using IE is still the best with Prime.
I have exactly same prime 2.2 and installed fixes/software/device packs.
I have no problem I can see all views. I use now IE 11, with Chrome 42.0.2311.90 and firefox 37.01 I have problems too with lots of views. You have not tell what browser + version you have.
Since you have same prime 2.2 as me. I have other problems, can you check yours?
Can you see a functional CLI template page at Configuration > Templates > Features & Technologies:
https://supportforums.cisco.com/discussion/12481691/can-cisco-prime-22-still-do-simple-ad-hoc-deployment-job-cli-over-all-switches
Do you have SNMP Connectivity Failed while Verify Credentials has no errors all green and checked.
