IGMP Querier in VPC domain

Hi
I am a little confuse with igmp querier on Nexus 5548UP
I have the following configuration on both VPC peers:
vlan configuration 208
ip igmp snooping version 2
ip igmp snooping querier 192.168.201.104
But the question is shell I use the same IP for querier on both VPC peers or diffrent ?

It doesn't matter. It's only a source address and nobody will send anything to that address. IGMP joins are sent to multicast address 224.1.1.1 .

IGMP Querier with Bluecoat ProxySG

Hi all
I ran into a problem with VIP for high availability on Blue Coat ProxySG. Both ProxySG send multicast packets
to advise the other ProxySG that it is up and the priority is contained in the multicast packet, along with the IP address of the VIP and so on.
This worked fine with Catalyst switches. Unfortunately it does not work over the newly installed Nexus switches.
There is no Vlan interface on the switches. The Vlan is only trunked through.
I found a hint that IGMP Querier could solve this issue. After configuration of IGMP Querier end acitvating Multicast on ProxySG
a IGMP group is built and all seems fine.
In a trace I can see IGMP Queries leaving the Querier but no answer from both ProxySGs.
After 6 minutes (3 times Querier Interval) the group disappears and both Boxes become active.
The topology looks like this:
Bluecoat1 -----N2k------2*N5k-----2*N7k-------Inter Datacenter Link-------2*N7k------2*N5k-----N2k-----Bluecoat2
                                    vPC         vPC                                             vPC          vPC
On both N7k in the left Datacenter is a Querier configured:
vlan configuration 85
ip igmp snooping querier 10.101.22.7
# sh ip igmp snoop querier
Vlan IP Address       Version   Expires     Port
85    10.101.22.7      v3        00:01:22     Switch querier
I wonder if an additional setting has to be made. Could it be that the Bluecoats ignore IGMPv3?
I would be very grateful for a hint.
Many Thanks!

Urs

Hi,
I am exeperiencing the same issue described above, with a similar network layout:
     BlueCoat1---N2K---2*N5K(vPC)---2*C6880(VSS)---Inter Datacenter Links---2*C6880(VSS)---2*N5K(vPC)---N2K---BlueCoat2
I have configured an IGMP querier in the BlueCoat VLANs on both 2*N5K(vPC), even if on one 2*N5K(vPC) should be enough.
For each VLAN I've used the same free IP-Address on all 4 N5K:
     Is that correct?
I am asking, bacause the Cisco-documetation says, that only the one with the "lowest IP-Address (?)" will be active:
     How should the IGMP-Querier-election work in my case?
Any help will be really appreciated.
Many thanks

Best Practice for VPC Domain failover with One M2 per N7K switch and 2 sups

I Have been testing some failover scenarios with 4 nexus 7000 switches with an M2 and an F2 card in each. Each Nexus has two supervisor modules.
I have 3 VDC's Admin, F2 and M2
all ports in the M2 are in the M2 VDC and all ports on the F2 are in the F2 VDC.
All vPC's are connected on the M2 cards, configured in the M2 VDC
We have 2 Nexus representing each "site"
In one site we have a vPC domain "100"
The vPC Peer link is connected on ports E1/3 and E1/4 in Port channel 100
The peer-keepalive is configured to use the management ports. This is patched in both Sups into our 3750s. (this is will eventually be on a management out of band switch)
Please see the diagram.
There are 2 vPC's 1&2 connected at each site which represent the virtual port channels that connect back to a pair of 3750X's (the layer 2 switch icons in the diagram.)
There is also the third vPC that connects the 4 Nexus's together. (po172)
We are stretching vlan 900 across the "sites" and would like to keep spanning tree out of this as much as we can, and minimise outages based on link failures, module failures, switch failures, sup failures etc..
ONLY the management vlan (100,101) is allowed on the port-channel between the 3750's, so vlan 900 spanning tree shouldnt have to make this decision.
We are only concerned about layer two for this part of the testing.
As we are connecting the vPC peer link to only one module in each switch (a sinlge) M2 we have configured object tracking as follows:
n7k-1(config)#track 1 interface ethernet 1/1 line-protocol
n7k-1(config)#track 2 interface ethernet 1/2 line-protocol
n7k-1(config)#track 5 interface ethernet 1/5 line-protocol
track 101 list boolean OR
n7k-1(config-track)# object 1
n7k-1(config-track)# object 2
n7k-1(config-track)# object 5
n7k-1(config-track)# end
n7k-1(config)# vpc domain 101
n7k-1(config-vpc-domain)# track 101
The other site is the same, just 100 instead of 101.
We are not tracking port channel 101, not the member interfaces of this port channel as this is the peer link and apparently tracking upstream interfaces and the peer link is only necessary when you have ONE link and one module per switch.
As the interfaces we are tracking are member ports of a vPC, is this a chicken and egg scenario when seeing if these 3 interfaces are up? or is line-protocol purely layer 1 - so that the vPC isnt downing these member ports at layer 2 when it sees a local vPC domain failure, so that the track fails?
I see most people are monitoring upstream layer3 ports that connect back to a core? what about what we are doing monitoring upstream(the 3750's) & downstream layer2 (the other site) - that are part of the very vPC we are trying to protect?
We wanted all 3 of these to be down, for example if the local M2 card failed, the keepalive would send the message to the remote peer to take over.
What are the best practices here? Which objects should we be tracking? Should we also track the perr-link Port channel101?
We saw minimal outages using this design. when reloading the M2 modules, usually 1 -3 pings lost between the laptops in the diff sites across the stretched vlan. Obviously no outages when breaking any link in a vPC
Any wisdom would be greatly appreciated.

Nick,
I was not talking about the mgmt0 interface. The vlan that you are testing will have a link blocked between the two 3750 port-channel if the root is on the nexus vPC pair.
Logically your topology is like this:
| |
| Nexus Pair |
3750-1-----------------------3750-2
Since you have this triangle setup one of the links will be in blocking state for any vlan configured on these devices.
When you are talking about vPC and L3 are you talking about L3 routing protocols or just intervaln routing.
Intervlan routing is fine. Running L3 routing protocols over the peer-link and forming an adjaceny with an router upstream using L2 links is not recommended. Teh following link should give you an idea about what I am talking here:
http://bradhedlund.com/2010/12/16/routing-over-nexus-7000-vpc-peer-link-yes-and-no/
HSRP is fine.
As mentioned tracking feature purpose is to avoid block hole of traffic. It completely depends on your network setup. Don't think you would be needing to track all the interfaces.

What is the best way to connect a firewall cluster to a VPC domain

Hi All
Can anyone help me decide what is the best way to connect a firewall cluster to a VDC running in a pair of N7K's which is a VPC domain?
Can I configure a VLAN interface on each VDC and use HSRP? I was planning on presenting one 10GB cable from each VDC to each firewall. Would this work OK? HSRP traffic will go across the VPC peer link correct?
thanks all

No, but the one caveat is vpc orphan ports. If the vpc link between the nexus switches fails for any reason, all the vpc ports on the vpc secondary switch will be forced down. So it's recommended to connect single port devices to the primary vpc switch so the connections stay up. But if you're ok with that, then I don't see any problems.
You have a few options, one would be to run a separate link between your nexus switches for non-vpc vlans. These vlans would not be allowed over the vpc peer-link, or forwarded out vpc's.
See here page 49 :

Firewall Connections to vPC Domain

Hi all,
What is the best way to connect a Firewall cluster (Checkpoint FW cluster) to a vPC Domain ?
Current Topology is like as below. We are gonna replace Cat6Ks with N7Ks.
FW#1(Active) ----- keepalive for amongt FWs -------- FW#2 (Standby)
     I                                                                               I
     I                                                                               I
     I                                                                               I
     I                 VLAN 100 HSRP on Cat6K Side               I
     I                                                                               I
     I                                                                               I
Cat6K#2 -------------------peer keepalive------------------------------Cat6K#2
           --------------------- peer link-----------------------------------
I know my options are :
Connect the FWs to an edge switch which supports etherchannel and connects to vPC domain through that port channel.
Connect the FWs through two ports (LACP config) to both N7Ks.
Setup a seperate STP link between N7Ks, configure VLAN 100 on this link and then keep running HSRP on VLAN 100 on both N7ks on this non vPC VLAN.
Setup the links between N7Ks and FWs as routed links and run a dynamic routing protocol in between.
Thanks in advance.

Hello all,
How about the option 1?
Our scenario is as below:
                   DMZ switch ----- PC
                    |             |
                    |             |
                    |             |
                  FW         FW   (Checkpoint with VRRP connecting to N7k using VLAN 16)
                    |             |
                    L2 Switch
                    | |           | |
                N7k-1 ---- N7k-2   (Peer Link Between N7k)
                    | |           | |
                    | |           | |
                   Inside switch ---- Server (VLAN16)
When user ping from DMZ switch PC to Server in the Inside switch, the packet loss and long response time happen intermittently.
But when we ping from Inside switch with another VLAN (VLAN12) to the server, it's okay. VLAN12 and VLAN16's gateway are on N7k with HSRP.
So N7k's inter-vlan routing seems to be okay, but through FW has problem.
L2 switch and Inside switch connect to N7k with vPC. ALL the PC/Server are in VLAN 16 and their default gateway is to N7k.
When user ping from inside to DMZ we can see a icmp redirect message, and I don't know whether it could be the problem to cause the intermittent packet loss?
Thanks.

Can I disable spanning-tree in a vpc domain ?

i have two N7718s in a vpc domain and each have a vpc connection to 300+ TORs(non cisco switch).
each 7718 have 300+ trunk port and a trunk port carring 80 vlans . so the logical port number is 300*80 = 24000
the problem is n7k r-pvst logical ports limit is 16000,it causes the vpc primary 7718 ping latancy time exceed 1000ms
2 ways to solve this problem : use mst instead of rpvst or disable spanning-tree
if i use mst , the logical ports limit is 90000, the problem will appear one day
so i want to disable spanning-tree . 7718s' vpc link to TOR use lacp ,it will prevent some layer2 loops. can i do it?

I have the same problem. :)

"Peer-switch" command on vPC domain and spanning-tree priority interaction

Hi guy,
We have 2 N7K (N7KA and N7KB) which will be running vPC in hybird and pure vPC environment.
I have a question about the Hybird and pure vPC environment. With the "peer-switch" command enable, should i tune the spanning-tree priority to be the same for all the vlan running on vPC on both N7KA and N7KB? This way, when i enter the "sh spanning-tree vlan X(vPC vlan) detail" command on N7K, it will list both N7K announc itself as "We are the root of the spanning tree".Also the switch running spanning-tree with N7K vPC vlan (Hybird), will see both N7K has the same priority (4096), and it is not desirable for a spanning-tree environment. Therefore, i used the "spanning-tree pseudo-information" on N7KB to tune the spanning-tree priority to "8192" and the switch running spanning-tree with N7K will list N7KB has a priority of 8192(perfect).
However, I notice some strange "show" output on the switch running Port-channel with the N7KA and N7KB. The "Designated bridge" priority is flapping as show on the switch. It is constantly changing between "4096 and 8192" with the same vPC system wide mac address.
Entering the "sh spanning-tree vlan X detail" command repeatly on switch with port-channel toward N7KA and N7KB.
>>sh spanning-tree vlan 10 detail
Port 65 (Port-channel1) of VLAN10 is root forwarding
Port path cost 3, Port priority 128, Port Identifier 128.65.
Designated root has priority 4106, address 0013.05ee.bac8
Designated bridge has priority 4106, address 0013.05ee.bac8
Designated port id is 144.2999, designated path cost 0

Number of transitions to forwarding state: 1

We have a issue similar to this in our environment. I am trying to upgrade the existing 3750 stack router with 2 Nexus 5596 running VPC between them. For the transition I have planned to create a channel between 3750 stack and 5596's. Once this environment is set, my plan is to migrate all the access switches to N5k.
The issue is when I connect the 3750 port channel to both N5Ks, all the Vlans on 3750 started to flap. If I connect the port channel to only one N5K everything is normal; but when I connect the port channel to both N5K running VPC, vlans are flapping. Any idea what is going wrong here? Am I missing something?

Qustion have 2 nexus 3000 setup in vPC domain, want to add the 3rd one, How is this done?

Multicast filter on SG300-10 and IGMP Querier

Hi
We're currently testing the Cisco SG300-10 for use with multicast TV services/channels but we're having trouble configuring the switch. Our setup is that we have a TV provider which is multicasting all their TV services into the switch's port 3. The multicast packets of a TV-channel should only be forwarded to another port in the switch if a client sends a IGMP join (report) message to start receiving a service.
First we've tried to disable multicast broadcasting by enabling Bridge Multicast Filtering Status (manual chap 15, "Defining Multicast Properties") but multicast packets are still broadcast on all ports. How do we filter multicast packets so they're not broadcast on all ports?
Also we need the SG300-10 switch to run as IGMP Querier so clients report membership at a regular basis. We've tried enabling IGMP Querier (manual chap. 15 "Configuring IGMP snooping") but it always remain disabled and we never see any IGMP Query messages (we use Wireshark to check this). How do we enable IGMP Querier?
When I press Apply the "IGMP Querier Status" remain "Disabled" in the "IGMP Snooping" page. Also the IP-address I specify is never transferred to the "IGMP Snooping" page.
Here's the switch's configuration:

Hm, solved multicast by filtering "Unregistered Multicast" and IGMP Querier by enabling IGMP snooping.

Query bind parameters domains

Hi
I use JDeveloper 10.1.3.10 and JHeadstart 10.1.3.
I use query bind parameters for domains.
When I use p_date=#{bindings.xxxx.inputValue}, it goes well. JHeadstart generates a map entry in the managed bean for p_date.
But when I use p_date=#{bindings.xxxx.inputValue!=null ? bindings.xxxx.inputValue : bindings.xxyy.inputValue}, JHeadstart does not generate a map-entry in the managed bean for p_date.
When I add p_date manually in the managed bean in the aaService-Domains-Beans.xml, then it works.
Does anyone know why JHeadstart does not generate the map-entry when using the "ïf"-condition?
Regards,
LvL

Hallo LvL,
Can't you use a blunt axe and do something like this:
#set ($bean = ${JHS.current.managedBean})
#set ($queryObject = ${JHS.current.domain})
<managed-bean>
 <managed-bean-name>${bean.beanName}</managed-bean-name>
 <managed-bean-class>oracle.jheadstart.controller.jsf.bean.QueryBindParams</managed-bean-class>
 <managed-bean-scope>request</managed-bean-scope>
 <managed-property>
 <property-name>namedParamDefs</property-name>
 <map-entries>
 <map-entry>
 <key>p_date</key>
 <value>#{'#{bindings.xxxx.inputValue!=null ? bindings.xxxx.inputValue : bindings.xxyy.inputValue}'}</value>
 </map-entry>
 </map-entries>
 </managed-property>
</managed-bean>Groeten,

Collection based query based on domain

Hello Everyone,
I am having a problem creating a custom collection in my SCCM enviornment
I want query based collection All Windows Operating
Systems except one domain ( In our environment we have 20 domain , in this i need to exclude one domain)
Could you help anyone to get this please

Understood Jeremy,
Do you have sub domains under the one you want to exclude?
Like sub.exclude.com under exclude.com?
We don't have child domain on this.
In our environment total 20000 machines are there. On the domain excluding having 9000 machines.
while I executing with this query i am getting total machines count is 17000 , suppose I have to get around 11000 machines.
Please help on this. I have to show my management today, because today is deadline for this. Please help on this

VPC+, aka L3 on back-to-back vPC domains

Hi,
Please consider this scenario, where L2 VLANS are spanning 2 data centers and where R1-R4 are L2/L3 N7K routers (replacing existing 6K).
(I wish VSS would be available also in N7K to make life 10x easier!!).
                      R1                  |                     R2
                       ||                    |                     ||
vPC peer-link ||    =======MAN=======   || vPC peer-link
                       ||                    |                     ||
                      R3                  |                    R4
                               Site A         Site B
Attached to R1 and R3 there are (dual-attached via 6K access switches) servers that may need to communicate to other servers in the same VLAN on the other side of the MAN. Over the MAN the VLANs are trunked, so its fine. This traffic can go over R1 or R3 both for L2 (vPC) and for L3 (HSRP vPC enhancements).
Anway, there is also a global OSPF domain for inter-VLANs communication and for going outside the DCs via other routers attached to the above cloud.

CSCtc71813) to have this kind of back-to-back vPC scenario to handle transparently L3 data (peer-gateway command should deliver also control-plane L3-info??). There are 2 workarounds available for this design:
1.       Define an additional router-in-a-stick using an extra VDC on each 7k. In this case, for example for R1 we would use 3 VDCs: 1 VDC for admin, 1 VDC for L2, 1 VDC for R1.
2.       Define static routes to tell each 7k how to reach the other 7k L3 next-hops.
a) What is the best workaround to choose in order to smooth the upgrade later to the version of vPC that will handles this issue?
b) Are there any more caveats I dont see? I havent seeen any link in CCO, so I am unsure how to proceed the design.
c) I would be tempted to think that using additional static routes is a better choice because it would easier to remove them once vPC+ is there.
What static routes shall I add? R1 to R2, R1 to R4 and so on and so forth? I miss the details of this implementation.
d) How would vPC+ looks like once (when?) is there?
Thansk for your valuable input in advance.

To expand on Lucian's comment, because I'm sure the next though will be...can I run OSFP over a vlan and just carry THAT over my VPC. You don't want to do this either.
We don't support running routing protocols over VPC enabled VLANs.
What happens is that your 6500 will form routing adj with each Nexus 7000....lets say Nexus 7000-1 and 7000-2. Note my picture below.
Lets say that R1 is trying to send to a network that is behind R2. R1 is adj to 7000-1 and 7000-2...we have equal cost paths. CEF chooses that 7000-1 to route the packet, however Etherchannel load balancing chooses the physical link to 7000-2. 7000-2 will need to switch the packet over the VPC peer-link to 7000-1. 7000-1 receives the packet and tries to send it out VPC member port to R2....however egress port drops the packet. This happens because we don't allow packets received from VPC member link send over VPC peer-link to be sent out another VPC member link.
I'd suggest to run an L3 link from your 6500 to each Nexus 7000 if you do want to do L3 on it.

Nexus 5500 Multicast Config Guide 6.x:
IGMP Snooping Querier
When PIM is not enabled on an interface because the multicast traffic does not need to be routed, you must configure an IGMP snooping querier to send membership queries. You define the querier in a VLAN that contains multicast sources and receivers but no other active querier.
When an IGMP snooping querier is enabled, it sends out periodic IGMP queries that trigger IGMP report messages from hosts that want to receive IP multicast traffic. IGMP snooping listens to these IGMP reports to establish appropriate forwarding
Example:
switch(config-vlan)# ip igmp snooping querier 172.20.52.106

Bernhard,
Here you go :-)
"ip igmp snooping" is no longer available under vlan mode. Please reconfigure under "vlan configuration <vlan-id>"
example:
Nexus5596(config)# vlan configuration 101 ( 101 is the vlan id)
Nexus5596(config-vlan-config))#ip igmp snooping querier 1.1.1.1 >>> here is the way to configure.

Query on Changing Domain Value ...

Hi All,
I have a requirement in which i have to change the Value range of a domain while executing a program...
Is there any FM available to achieve this functionality.... Kindly provide pointers to achieve my requirement...
Regards,
Navin.

Hi
I have already replied this in my earlier post.
Use the following Function module - RPY_DOMAIN_READ to read the Domain values in a program and use them as per your requirements.
Sample code
CALL FUNCTION 'RPY_DOMAIN_READ'
 EXPORTING
 activation_type_i = 'M'
 doma_name = 'DOMAIN' <<<<<- UseYour domain name here
 language = sy-langu
 TABLES
 doma_values = i_values <<<--- Returns domain values
 EXCEPTIONS
 cancelled = 1
 not_found = 2
 permission_error = 3
 illegal_type = 4
 OTHERS = 5.
IF sy-subrc <> 0.
ENDIF.
Incase you need any other details, let me know.
Hope this will help.
Please reward suitable points, incase it suits your requirements.

Domain index query takes 12 hours to execute

Hi Friends,
My query which uses domain index takes 12 hours to execute. Can you please help me tuning this query?
select /*+ NO_UNNEST ORDERED index_ffs(Term idx_recanon_term_ysm1) parallel_index(Term, idx_recanon_term_ysm1, 8) */ term.rowid
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where cmpgn.recanon_search_terms.search_type=3 and
contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0 and
Term.pod_id=11
Thanks in advance.
Regards
Bala

First your driving table is recanon_search_terms to get the required search terms, then use them to query Oracle Text. What you are trying to do is to get a subset of table term first and than run every individual row of table term against the search terms. This approach will take a very long time.
Not sure what you want to do, but it looks something I have been working on previously. As far I can see there is a table with controlled terms which are matched against other raw terms in a text document using Oracle Text. The issue is that you do a join in the contains clause without knowing the number of query expressions formed. It can be that 7 thousand individual queries run at once, than use indexes of the other predicates, do some sorting, etc. which would explain the long time needed. It will probably run out of memory causing all sorts of issues.
As a quick fix try first following statement without hints.
Tell us how many rows you get, the distinct counts for pod_id and search_type and how long it takes.
CREATE TABLE test_table AS
select term.pod_id pod_id, cmpgn.recanon_search_terms.search_type search_type, term_primary_key, ....
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0
Create index test_idx on test_table(pod_id, search_type) and use test_table instead to get the results, just by providing pod_id and search_type without the join in the contains clause.
SELECT ..
FROM test_table
WHERE pod_id = X
AND search_type = Y
Maybe this approach is sufficient for your purpose. For sure, it will give you instant results. In that case a materialized view instead of the table could work for maintenance reasons; I had some issues with materialized views for above scenario.
However check very carefully the results. I would have some doubts that all rows in search_text form a valid query expression for Oracle Text. If search_text has just single tokens or phrases wrapping curly brackets around will probably resolve the issue.
Think about to form one query expression through a function call instead of a table join inside the contains clause. Sometimes to run a set of individual queries are faster than one big query.
select term.rowid --, form_query_exrpession(3) query_exrpession
from cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT, form_query_exrpession(3)) > 0
The above function will form one valid Oracle Text query expression by using the table recanon_search_terms inside the function. This approach normally helps, at least in debugging and fine-tuning. Avoid using bind variables first in order to identify highly skewed distribution of search_type.
The other performance issue is the additional predicate of pod_id = X, here the suggestion from radord works very well. If you want to get your hands dirty have a look at user_datastore in the Oracle Text documentation, this will give you all the freedom you want.
