Sun Cluster & Multiple MAC Address on QFE

Is it possible to have multiple MAC addresses on a QFE that is also used for the private interconnect and set local-mac-address?=true at the prom on systems running Solaris 7 and SC 2.2 and Solaris 8 and SC 3.0 12/01

Sun Cluster 3.1 is required.

E4200 v2 - Uses multiple MAC addresses for the same device

This unit seems pretty good at first but on looking at the Web interface I noticed that it was using multiple mac addresses for the same device and showing devices on the lan on the Wireless side and other odd things.
After a week of running it the home server network started to get erratic, it would seem to all point to dns and dhcp issues in the router.
Seems the V1 had the same issues that they did not fix on this.
The Cisco connect software shows 5 devices the Web based utility shows 3??.
Its pretty bad that they charge nearly $200 and cannot be bothered to finish the unit or address the issues that were in V1.

I am afraid I didn't get the clear picture of the issue mentioned in the post. Could you please elaborate a little bit? If you connect a device/computer wired and then later you connect it wirelessly. It is obvious that you would get to see two different MAC addresses for the same device, one for the LAN adaptor and other one for WLAN adaptor. If that is what you are referring to?
Secondly, may I know, what issues did you face with DNS and DHCP in the router? Is it not able to resolve the DNS or something else or DHCP is not sending IP address to the clients?

Sun cluster: virtual IP address

Hi,
What is the virtual IP address and how to configure it?
For example, should it be defined in /etc/hosts? dns?
Thank you,

[[[s this correct to have apache HA?]]]
Apache can be set up as a failover resource (so it is active only on one node at a time) or a scalable resource (where it would be active on multiple nodes at the same time).
[[[Just an aside question: HAStoragePlus is NFS sharing? What is difference between NFS resource and mount resource (I saw Veritas differentiate between them)? In case I set up a shared disk, is it NFS or mount resource?]]]
HAStoragePlus is not NFS sharing. HAStoragePlus let's you create HA storage (it's called HAStoragePlus because there was an earlier generation data service (aka Clustering Agent a-la VCS) called HAStorage). This will let you wrap a shared storage device and fail it back and forth between multiple nodes of the cluster.
NFS sharing has to be handled using the SUNW.nfs Data service (or in other words, the NFS clustering agent) (ie only if you want to set up NFS as a HA service). Otherwise, you can use standard NFS.
Mount resource is (i'm guessing here) any resource that can be mounted. In other words, a Filesystem.
NFS resource is a resource that is shared out via NFS.
[[[Also, a basic question: The shared disk should not be mounted in /etc/vfstab. Correct? It should be only present when doing format on each node. Right? It is SCS that manages the mounting of the file system? This should be up before testing apache HAno?]]]
That is correct. Sun Cluster will handle mounting/unmounting the filesystem and importing/deporting the disk set (in Veritas world it is called a Disk group).
When you build your cluster resource group (aka VCS Service group), you will have to build the dependency tree (just how you would in VCS).
1) Create empty RG
2) Create HAStoragePlus Resource
3) Create Logical Hostname resource
4) Create Apache resource
5) define dependency of Logical hostname (Virtual IP) and HAStoragePlus (filesystem) so that apache can start.
At each stage, you can test whether the RG is working as it should before proceeding to the next level.

ACE multiple mac-address for a single IP (solaris ipmp)

Dear All,
We are triing to load ballance smtp traffic to solaris mail servers that are using ip multipath in bridge mode configuration.Multipath is configured so that only one of the redundant interfaces replies to arp request. Therefore all of the traffic come to the solaris from the ACE on the primary interface, but solaris uses the secondary interface too with different mac address to answer.The load ballancing working correctly it does not matter if solaris answers the request with its primary (MAC known by ACE) or secondary interface (MAC not know by ACE). But if the solaris wants to create a tcp session that is not balanced but go through the ACE with secondary interface which mac-address is not know by ARP in the ACE, the packets are silently discarded. There is no logs about it.
Please if someone could know this behavior answer.
Regards,
szicsu

If you do a 'show np 1 me-stat '-socm'' you will see a counter catching the packet drops.
Drop [mac lookup fail]: 30 0
Drop [route lookup fail]: 14316 0
We can't setup connection for unknown mac-address or if we do not have a route.
We need to first learn the mac-address through the arp request/response mechanism.
This is during this process that the encap id is associated with the mac-address.
Without that encapid we can't create the connection to flow the traffic.
You can try to disable normalization to see if that could help, but I can't guarantee it.
Gilles.

Cisco ISE 1.1.4 Patch 7 (Internal Endpoint Mac Addresses Getting Disppeared)

Hi Folks,
I am having issue that mac addresses which we are trying to add under Internal Endpoint Group for MAB getting disappear automatically after few minutes. We tried multiple mac addresses but result same. We can see the mac address which we added earlier but new mac address getting disappear. Is there any limit to add mac address under Internal Endpoint. We have following licenses.

Thanks

Tabish,
We'll update the latest patch and then look for the work around from any one of our Cisco experts

Show Mac Address Table in ASR9k running XR

I'm trying to find a Mac Address in the ASR9k table. We have a server with multiple mac addresses and we need to know what MAC is being learned by what interface.
Thank you,

Use the command
show l2vpn forwarding bridge-domain <group_number>:<domain_name> mac-address location 0/x/CPU0
or
show l2vpn forwarding bridge-domain mac-address location 0/x/CPU0

Mac Address Table

Hello,
In one of our core switches, the output of the mac-address-table shows some mac addresses which come up as MPLS Multicast address when I looked them up under MAC Manufacturer(See below). Also, in the mac-address-table under the port column, those mac addresses display several ports associated with them and the word Router(see attachement). My question is, why are these MAC addresses come up as MPLS Multicast and why under the ports is it has the word Router?
Thanks in advance...

Hi,
Yes multiple MAC addresses are supported on each port. The switch learns the MAC by noting the source address of the packet received on each port and on that basis it builds what we call MAC address table. There is an aging mechanism in place which removes the inactive MAC addresses and allows new ones to be learned as devices are connected and disconnected.
The default aging time is 300 seconds, however if need arises you can change the same by giving the command - 'mac address-table aging time number vlan vlan-id'.
Have a look at the following link-->

Simple : Which src MAC address when WLC bridges 802.11to 802.3 ?

When a WLC bridges 802.11 to 802.3, after extracting the original 802.11 frame from LWAPP, does it put the 802.11 senders
MAC address as the source addr in the new 802.3 frame ?
Or does it put the WLC's AP manager interface ? (Or the WLC's Management Interface) ?
If you refer to :-
http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp1050985
One of the bullet points reads :-
After processing the 802.11 MAC header, the WLC extracts the payload (the IP packet from Host A), encapsulates it into an Ethernet frame, and then forwards the frame onto the appropriate wired network, typically adding an 802.1Q VLAN tag.
Should it include :-
and adds the MAC address of the Wireless client as the SOURCE MAC ADDRESS to the outgoing Ethernet Frame??
Also, will an ARP for a wireless client yeild the mac address of the WLC or the AP ???
Thanks

It looks like the src address of the original 802.11 client goes to the 802.3 frame as the source.
So am I correct in thinking that (in a flat topology, no L3 routing) the WLC will appear as to an attached switchport as trunk
(not necessarly 802.1q, but usually) with multiple mac address learned from it.
Any host on the LAN will send a packet for DEST MAC, which will eventually be SWITCHED (via L2 switching), upto the WLC.
The WLC will then send it over lwapp to the AP, and the AP will send it to the client.
But as far as the mac-address-table is concerned of any switch directly attached to the WLC, it will see
all client MAC address for ALL wireless stations for ALL AP's... Correct ?
Thanks

Multipe mac addresses entries for the same port (FE)-Switch 3560

Dear All,
I have a problem with a host whitch is connected to 11 port of my cisco 3560. from time to time the, the connection is lost with the host and after some troubleshooting i see two entries of mac-address table for the port 11.
I'm asking if someone has an idee how to explain this issue and how to see if this port is participing to SPT or...
I see also somme error of collision :

i have two routers in the same switch: my wan router + un other router used to conneced some separated hosts to internet.
If i use statif addressing for the second subnet (2 hosts + internet router), is there any risk for collision or broadcast domains or errors ?
is the second router distrub my LAN or WAN ?
Manay thanks for your help and support.
Best regards,

Hello,
For the first part of the question, I guess somebody might be connecting a hub to that port. If the hub is not negotiating the speed/duplex with the 3560 switch, then that port will go to half-duplex mode and you will see collisions on the port. That might also explain why you are seeing multiple MAC addresses on that port. Please check the port to see if the hub is connected and remove it. You can use features like port-security to ensure only one MAC address is registered on that port and people are not connecting hubs/dumb switches on that port.
For the second issue, you can certainly use static IP addresses as long as they are not overlapping with other subnets in your network. If they are overlapping, you do need to configure NAT on the router so that they are not affecting rest of the network.
Hope this helps.

Mac address cloning / BT Home Hub 5

I have Infinity 2 package with BT Home Hub 5.
I recently bought Asus AC3200 and would like to use it as a main wired/wireless router in the house.
I don't want to have an extra routing hope, so I thought to setup Mac address cloning, so AC3200's broadband interface has the same MAC as BT Home Hub.
Is it possible ?
Where can I find MAC address of BT Home Hub 5 broadband interface ?

Are you trying to connect a 2nd router to the phone line at the same time? If so it won't work. If not why are u trying to clone the mac address? You can only have the same Mac address once within the same network. Arp cannot understand multiple devices with the same Mac address. You can only have a mac address known to one device. Multiple IP addresses can map to the same Mac address but you cannot map the same IP address to multiple Mac addresses.

Multiple IP adress on one mac address?

Hi!!
I have a WLC 2504 and AP 1602. Is it possible to give the client multiple ip addresses with one mac address. If yes, how it's made on WLC or AP?

In certain cases there is a need to have multiple IP addresses responding beyond a single client wireless association. For example, some video cameras will have an internal communication module that tied to wireless interface via ethernet. Some PoS devices may have similar requirement.
In WLC there is an option WLAN->WirelessID->Advanced->Passive Client.
Now I am not sure if this will work with multiple IP addresses tied to the same MAC or not.

I want to use Mac Mail for my work email address, which containts multiple outbound options (i.e. hr@, me@ etc). Is there a way to set up Mac Mail to have an account with multiple outbound addresses rather than adding in multiple accounts?

This sounds like the age old problem with keychain & Safari. I don't know of a way to solve it without using something like 1Password.
The iOS app has it's own built in browser, so it has more control over what gets autofilled. Safari on OS X has an 1Password extension that handles account selection & autofill etc.
Keychain is great in principle, but it quickly falls down when you need tight integration with many ID's & different use cases (work, home etc).
I'd suggest you submit feedback to Apple about your thoughts. I did so years ago about this issue & this is how far we have come (back to the point where me.com synced passwords) :^)
http://apple.com/feedback/macosx.html
Other tools like lastpass or keypassx may also help if you want to truly segregate password storage, but that doesn't fix autofill, the way around that issue is to dedicate one browser for work.

Can I sync multiple .mac accounts with my address book???

i have an idisk membership with 5 email accounts. i finally got around to syncing my address book to my .mac account. in doing this i found that i had to sync from my 'master' account. it worked fine, but when i sign on to one of my other .mac accounts my contacts are not there in the address book.
can i only sync to the master account??? if so, this really ***** because i have multiple email addresses for various tasks (business / personal / junk). i'm really gonna be bummed.
any help greatly appreciated!!!

Sync Mac Address Book - multiple Google accounts

I hope this is the right place for this question.
I understand that you can sync the Mac Address Book with Google accounts, but is there a way to sync that Mac Address Book with MULTIPLE Google accounts.
Our scenario is that we have one iMac as our main database, and want to sync it to mine, and my wifes Google account.
Thanks for any help.

I have found a program called Spanning Sync

It allows for multiple Google syncing

Multiple Oracle databases in Sun cluster 3.2 (without RAC setup)

There are 2 Sun SPARC (Sun Fire T2000) servers with Solaris 10 (05/09) OS and Sun Cluster 3.2 software. We need two different Oracle databases & instances (Oracle 10g R2 without RAC) for an application. The first database is for Production and need to be configured in the first node & Shared storage disk and need high availability. This database should run from the second node if the first node fails. The second database is for Quality/Test and it is prefered to be running in the Second node for better load distribution. This DB doesnt require any failover.
The shared storage is Sun SE 3510 FC and multiple LUNs can be created for different databases..
Is it possible to configure two different resource groups (one for Quality and other for Production) and make the first node primary for Production RG, and the second node primary for Quality RG and thus distributing the load on 2 servers ? If possible, what special configuration required in Sun OS and Cluster side ?
Appreciate if you can give some configuration procedures/documents for this multi-master cluster setup..

You can configure two resource groups, such as:
# clrg create -n node-a,node-b prod-rg
# clrg create -n node-b qa-rgand you configure the required resources (disk groups / file systems, logical host, oracle listener, oracle server) as described within
[http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand|http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand]
Note that this is not really called a "multi-master" configuration - that has a specific meaning for a resource group (see [http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view] ) for details.
With Solaris Cluster all nodes part of a cluster are considered active and can host resource groups. You can have any number of resource groups running, where a subset runs one one node, another subset on other nodes. The nodelist property of the resource group defines where it can run, the first node in the list is the preferred primary.
You can even define resource group dependencies or affinities between the resource groups. Like you could define a negative affinity between qa-rg and prod-rg, such as if prod-rg needs to failover to node-b (since e.g. node-a died), it would offline qa-rg. Details for that kind of possibilities are described at [http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view].
