Tacacs per vrf no supported on MLS C3750G
HI,
As i already know the tacacs per vrf not supported for MLS C3750G and some other old versin of the IOS router or switch, but now i have 2 vrf routing tables configured in my switch is there any work around for this thing to work?? really aprreicated your inputs guys!!!
Thanks for the response but I post the question after knowing that, I already checked on Feature Navigator that THIS IS NOT SUPPORTED for my router, at the end of my configuration I am purposing a workaround using a tunnel to bybass the nonsupported configuration.
My question to you is, does a configuration with gre with vrf can work instead of the nonsupported configuration?
I know that the alternative is to run Radius but it is more paperwork to do than trying to implement a solution with the current IOS.
Thanks and sorry if I didn't make self clear at the beginning of my first post.

Tacacs per vrf no supported on my router, does a gre tunnel would work?
Hi,
Basically the problem is that I am working with old routers, checked already on feature navigator an the following commands are not supported on the router to communicate to a TACACS server that resides on a vrf:
Configuring Per VRF for TACACS+ Servers: Example
The following output example shows that the group server tacacs1 has been configured for per VRF AAA services:
aaa group server tacacs+ tacacs1
server-private 10.1.1.1 port 19 key cisco
ip vrf forwarding cisco
ip tacacs source-interface Loopback0
ip vrf cisco
rd 100:1
interface Loopback0
ip address 10.0.0.2 255.0.0.0
ip vrf forwarding cisco
Basically I can not support all the above, however I was thinking of bypassing the command creating a GRE tunnel, I just need a confirmation if the following would work, if not I would appreciated that someone can point me into a better direction:
ON BRANCH ROUTER:
int l0
ip add 1.1.1.1 255.255.255.0
no shut
int tun10
ip add 2.2.2.1 255.255.255.0
ip vrf forwarding cisco
tun so l0
tun dest [ip add of router directly connected to tacacs server]
ip tacacs source-interface l0
tacacs-server host 10.10.10.1
tacacs-server key 7 cisco
ON REMOTE ROUTER:
int l0
ip add 3.3.3.3 255.255.255.0
no shut
int tun10
ip add 2.2.2.2 255.255.255.0
ip vrf forwarding cisco
tunn so l0
tunn dest [ip add of branch router]
Attached is some real information, the ip address of the real tacacs server is 10.20.30.61.Thanks for the response but I post the question after knowing that, I already checked on Feature Navigator that THIS IS NOT SUPPORTED for my router, at the end of my configuration I am purposing a workaround using a tunnel to bybass the nonsupported configuration.

Gooday
Im trying to configure tacacs per Vrf but no luck, i been using docs from cisco, can somebody help me if my config is correct?
here is my current config
aaa group server tacacs+ tacacs1
server-private 183.x.x.x key 7 XXXXXX
ip vrf forwarding NMS
ip tacacs source-interface Vlan89
aaa authentication login default group tacacs+ enable
aaa authentication enable default group tacacs+ enable
aaa authorization commands 0 default group tacacs+ none
aaa authorization commands 1 default group tacacs+ none
aaa authorization commands 15 default group tacacs+ none
ip vrf NMS
description OOB NMS VRF
rd 110:100
interface Vlan89
description to DIA monitoring
ip vrf forwarding NMS
ip address 183.109.191.11 255.255.255.0
end
ip vrf NMS
thanksthanks Carlos,
I followed your suggestion, i think there will be only change in the aaa authentication statement,
I'm very careful on changing the aaa statement, and don't want to change it without your expert advice, the router is located in different country and no one will reboot if i lost the connection
The first "password" prompt you get is for the local enable password? We might need to enable "Debug aaa authentication" and "debug tacacs" and recreate the issue.
ans: yes, first it will ask for the local password
below is the debug

Per VRF Tacacs+ support on 3550EMI
Trying to get Tacacs+ running on a 3550EMI switch running 12.1(22)EA3 (latest release), without much success due to wht appears to be lack of support for for Per VRF AAA/TACACS+ on the box.
Checked elsewhere and looks like this feature is only available in some 12.2 and in 12.3T, but does anyone know if vrf-aware TACACS+ it is likely to appear on the 3550EMI or indeed on 12.1? Or does anyone know of a work around? (tried specifying a source-interface but this doesn't work)
TIAThis feature was introduced in 12.3(7)T. I guess its not supported on the Switch currently.

Per-VRF TACACS config gets "Address already in use" error
I have created a per-VRF TACACS config on a couple of network devices. I can ping the ACS servers through the VRF. TACACS makes the attempt to contact the servers, but the following message shows up in the log when I debug TACACS:
*Mar 11 08:57:38 starts: TAC+: Opening TCP/IP to x.x.x.x/49 timeout=5
*Mar 11 08:57:38 starts: TAC+: TCP/IP open to x.x.x.x/49 failed -- Address already in use
I can't find anything on CCO that references the "Address already in use" message.
Has anyone run into this?Hmmm...no, the server group is still there. Did you see the other post which describes the bug ID? The link to the bug is:

Do you get the IP address is in use log message? -

I know some of this config is redundant but I have been trying different things and getting nowhere.Hi,
Your debug output shows time out to ACS server as below.
Feb 4 11:39:21.372: TAC+: TCP/IP open to 192.168.5.76/49 failed -- Connection timed out; remote host not responding
Feb 4 11:39:21.372: TAC+: Opening TCP/IP to 192.168.5.76/49 timeout=5No authoritative response from any server.
Feb 4 11:39:26.372: TAC+: TCP/IP open to 192.168.5.75/49 failed -- Connection timed out; remote host not responding
Considering the fact that you are not able to see any logs on ACS, that means traffic may not be reaching the ACS.
Have you tried pinging the ACS server from the switch mgmt vrf? Your previous example was showing ping responce to the managment workstation (192.168.5.85) and not to the ACS.
Hope that helps

SUP720 MPLS support only 700 routes per VRF?
In following document i found that SUP720 supporting only 700 router per 1 VRF. Am i right?
http://www.cisco.com/en/US/partner/products/hw/modules/ps4835/products_data_sheet09186a0080159856.htmlThere is no such thing as a limit of 700 routes per VRF. What is described in this URL is that scalability testing has been performed with 1024 VRFs with 700 routes each (1024*700=716800 routes total).
You could go way beyond 700 routes per VRF if you don't plan to provision that many VRFs.
Let me know if I answered your question, -
Hello,
in my lab i have 3 sites each with 3 VRF's configured. A diagram ist attached. I like to configure fixed bandwidth for each vrf. the central vrf should have 768 kbps and the the other ones ones should have 256 kbps each.
What are the options i have to achive this?
Thanks a lot in advanced
AlexHi Alex
Since you have already policed the bandwidth at the access, would there be any excess bandwidth that will leak from this policing.
Besides, ideally you would configure your core with a standard llq+cbwfq config and give priority to voice. You will in production have multiple customers and you cant have sich a bandwidth restriction in place.
Also, no you cannot police bw in core per vrf. But at the same time I can think of a non-conventional way of doing it by using TE but that is a very bad way of doing it.

Does anyone know if it is possible to enable Per-VRF BGP Dampening? I have a router running 12.4(9)T and when I enable BGP dampening within an address-family, it is enabled under all routing contexts and within VPNV4.
Any ideas?
JonHello Jon,
try to give the command only under the address-family of interest
it should be supported
Command Modes
>>Address family configuration
Router configuration
see
http://www.cisco.com/en/US/docs/ios/iproute/command/reference/irp_bgp1.html#wp1012660
Sorry, I haven't seen you had already done. This may be a bug in your release.
As a workaround you could try to use a route-map like in this example:
Router(config)# router bgp 50000
Router(config-router)# address-family ipv4
Router(config-router-af)# bgp dampening route-map BLUE
Router(config-router-af)# end

Per VRF label or Per route label
Folks,
A few weeks back I saw on some study group somewhere that im on a decent conversation on the downfalls of per vrf labels (juniper) compared to per route label (cisco). Now per route label obviously has its limitations in label consumption but per vrf label threw up a few issues - one of which was something to do with sub optimal routing. Anyone know any downfalls of using per vrf label space?Rob,
One of the disadvantages of per VRF label scheme is that it requires an IP lookup on the edge router. This is due to the fact that if the label is shared among all CEs on a given PE, an IP lookup needs to be done in the VRF to determine which CE we should send the label to.
Another disavantage would be that you couldn't support CsC using a per VRF label since an IP table lookup is required on the PE, which breaks the end to end LSP.
On the other hand, you are absolutely right about the increase resources comsumption when a per route label scheme is used. This affects some vendors more than others though.
Hope this helps, -
Hi,
Would like to know if per VRF label is supported on 7600 platform with SUP7203BXL?If yes can anybody share the config detailsAnup,
It is currently supported via the following hidden command:
[no] mpls label mode { vrf | all-vrfs } protocol bgp-vpnv4 { per-prefix|per-vrf}

Essbase error currently multiple reports per retrieval not supported
Hi,
One of my users got this error message while working on Essbase Excel add-in. "currently multiple reports per retrieval not supported". Any suggestions why do we get this error and what changes have to be to made to avoid it?
Thanks,
JunaidIt's kind of a catch-all error message, usually spurred (so I guess that isn't really a catch-all) by having the same dimension referenced more than once in the sheet, e.g., Product in the grid point of view and in rows going down or a dimension repeated in the grid point of view.

Can you help me? Thank you.
Romanif the main server is up, the CSS will use it over the sorry_server.
You can't tell the CSS not to use it if it is UP.
Therefore, the only solution is to find a way to keep your main server down once it fails a keepalive.
This can be done with a script that would issue the command 'suspend' once it detects the service missed a keepalive.
The script can be a tcp keepalive script and instead of returning just a failure one the server is down, the script itself can generate the 'suspend' command.
So, you then have time to sync your database and when ready you can do an 'active' under the service to start using it again.

On Nov. 22, after having to erase and restore my WD My Passport for Mac external hard drive (per WD tech support) then rebacking up the iMac, I noted that three events loaded into iPhoto in Sept., Oct. and early Nov. had disappeared. They certainly had been there because I printed out several images from these events. Now they have vanished but everything through August and after Nov. 22 is there. Seems impossible. How could something disappear from the hard drive? Apple tech was unable to explain or provide a solution. Has anyone else ever had something like this happen?
How did you reformat the EHD? It should be OS X Extended (journaled) with ownership set to be ignored.
If the drive is formatted correctly do the following:
1 - launch iPhoto with the Command+Option keys held down to open the First Aid window. Be sure to follow the circled recommendation in the screenshot.
2 - run Option #4, Rebuild Database. -
Tacacs Authentication - VRF ?
Hi !
Our Management LAN for accessing the switch is reachable through a VRF.
I tried to configure TACACS+ for User Authentication - by specifying "ip tacacs source-interface vlxxx".
This vlxxx is member of this Managment-VRF.
But the switch does NOT send any TACACS request through that particular VRF.
Could you plz help me ?
thx
