Configure active and standby mac address in failover
Hi guys,
I just have a doubt that, if I configure the active and standby mac address in failover, does it will cause any downtime?
As I planning to configure the active and standby mac addresses in failover during production time and not wish that it will bring any downtime to me.
Besides that, just need some guideline that do I need to put all the interfaces' mac addresses in failover?
failover mac address GigabitEthernet0/0 0022.90fe.2000 0022.90fe.2001
failover mac address GigabitEthernet0/1 0022.90fe.3000 0022.90fe.3001
failover mac address GigabitEthernet0/2 0022.90fe.4000 0022.90fe.4001
failover mac address GigabitEthernet0/3 0022.90fe.5000 0022.90fe.5001
Hi Marius,
Seem like set the failover MAC address was not working for me.
Last friday I was tested the failover MAC address.
TEST 1
1, Power off primary ASA and secondary ASA work as active.
2, 2821 router able to learn the correct arp entries.
TEST 2
1, Power on primary ASA and failover from secondary to primary.
2, 2821 router able to learn the correct arp entries from ASA.
3, Set failover MAC address, power off primary ASA and secondary ASA be active.
4, 2821 router unable to learn the correct arp entries.
TEST 3
1, Removed failover MAC address from secondary ASA.
2, 2821 router still unable to learn the correct arp entries from ASA.
3, Power up primary ASA and secondary ASA still in active.
4, 2821 router still unable to learn the correct arp entries from ASA.
5, Reboot 2821 router and it able to learn the arp entries from ASA.
I am not sure this issue from router or from the ASA. But I guess I will try to upgrade the router in term of software and hardware.

RV016: PPTP Server and "Block MAC address"
So if the PPTP server is enabled, and "Block MAC address not on the list" is enabled under the DHCP settings, will the PPTP client get an IP address?
Similarly, if the PPTP server is enabled and the range of IP addresses configured on the PPTP server screen is outside the IP range of the router due to a subnet mask (like 255.255.225.248 for example), will the IP still be assigned to the PPTP client? If assigned, will that IP have any connectivity to the LAN?
Thank you in advance for any answers!
Huntsville's Premiere Car and Bike e-magazine: www.huntsvillecarscene.comSo here's how PPTP works with these two features:
1. The PPTP IP range is a different range than the DHCP range. You get an error message if your PPTP IP range overlaps with the DHCP one.
I didn't test the 'Block MAC' function because since the IP isn't coming from the DHCP pool, I highly doubt any MAC blocking will work.
2. Since your PPTP IP address range is outside of the DHCP range, this point is completely taken off the table. However, if you choose an IP range that's outside of the subnet, you'll get an error message when saving. I also learned that if you set the PPTP IP to just a single number and connect, the router will automatically reject any additional connections since no IPs are available.

CSCuc72466 - Spine Control Bus fail in both active and standby - 2
Hello,
we have running Version 5.2.(7) on "Nexus7000 C7010 (10 Slot) Chassis with 2 "Supervisor module-1X" N7K-SUP1
our system is affected by this bug today.
mery cristmas and happy new year!Spine Control Bus fail in both active and standby
CSCuc72466
-->
Description
Symptom:
SpineControlBus diagnostic test failure on active and/or standby supervisor.
Conditions:
This happens when active and standby supervisors run the Spine test at the same time.
Workaround:
Configure the following for the module in question (only one SUP, even if both have the error):
NOTE: Test 11 is for Sup1, Test 10 is for Sup2
N7K(config)# no diagnostic monitor module 5 test 11
N7K(config)# diagnostic clear result module 5 test 11
N7K(config)# diagnostic monitor interval module 5 test 11 hour 0 min 0 second 31
N7K(config)# diagnostic monitor module 5 test 11
N7K(config)# diagnostic start module 5 test 11
This workaround will decrease the possibility of this condition occurring but does not guarantee that the diagnostic failure will never be encountered. For that the customer needs to upgrade to the proper code with this fix.

Sync config between active and standby CSM
Is there a way to sync config between active and standby CSMs? Just as one that in CSS.
How about two SSL Service module in two different 6500 chassis?
Thanks.HI,
there is right now no command to commit redundancy between two CSM-Modules. Maybe in the future there will be one. Okay in regards of sync the only way is to check for redundancy is the show mod csm x ft command. But be aware that some slight differences like a real not being in service are sometimes not recognized.
In regards of the SSLModule there is no way as far as I know to sync them. This won't be present in the future in my opinion as there are certificates which require a password or something like that and one won't be able to do redundncy without those passwords. So In my opinion no way to sync two SSL-Module because of security issues.
Kind regards,

Goldengate between active and standby database server
Hi:
I want to make goldengate connection between active and standby database servers (bidirectional). is it possible?
if yes what steps is required rather than active-active connection.
PLease help!!!
Regards,
AbhishekWhat do you mean by "standby" server? If you are referring to a Data Guard standby, how would bidirectional work? That's why one is primary, the other is standby.
If you are doing A-A, your "standby" is just another master in the N-way master architecture, so you already have a bi-di setup, right? Are you looking to replace Streams with GG? -
Hi. I'm trying to set-up the wireless access times in my Airport Utility. I need to enter the "Description" and the "MAC Address" of each wireless client before I assign access times. What are these? Thanks.
Let's say that an iPhone is one of the wireless clients that you want to allow access to the network.
The Description of this device is anything that you want to specify for easy identification purposes. For example, the Description might be something like......
Rex's iPhone
The MAC Address, also known as a Wi-Fi Address is a unique indentifiction number that is assigned to every device. The number will always follow this form:
xx : xx : xx : xx : xx : xx, where "x" could be a number or letter.
To find the MAC Address or Wi-Fi Address of an iPhone or iPad.....
On the Home screen.....
Tap Settings
Tap General
Tap About
Wi-Fi Address is the item that you want
If you have a Mac computer......you can find the MAC Address or Wi-Fi Address as follows:
Open System Preferences (gear icon on the dock)
Open Network
Click on Wi-Fi on the left
Click Advanced at the lower right
The Wi-Fi Address for the Mac is located at the bottom of the window
Other wireless devices usually have the MAC Address or Wi-Fi Address on the label on the back or bottom of the device -
Spanning Tree and Admin mac address issues srw2048
Ok, I have a somewhat complex problem and hopefully someone may shed some light or have an idea as to whats wrong.
First the scenario:
I have two Cisco Cat 6509's etherchanneled to each other via two fiber cables. One of these is the STP/RSTP root. I have two SRW2048's.. one trunked to each of these 6509 switches. There is also a trunk between the SRW2048's. All this is to create a redundant topology so that if one of the switches fail's the others can still forward packets to each other. Of course the scenario described is in fact a loop that should be handled by STP/RSTP. I have RSTP enabled on all the switches in the scenario (PV RSTP on the cisco switches as they only do Cisco's brand of per vlan spanning tree). There are 3 vlan's configured on each of the srw2048's (2,55,96). There are corresponding vlan's also on the 6509's. I have put the srw2048's management interface into vlan 2.
The problem:
I need to forward packets between the srw2048's primarily and only use the 6509 that is not the root when a failure happens. I have configured the non-root 6509's spanning tree cost on the etherchannel to be higher then the alternate path through the srw's to the root. I can hook everything up and view the spanning tree and see that the srw2048's interface that goes to the non-root 6509 is blocked, and all other interfaces on the other switches are forwarding. I can in fact ping and get to the admin interface on all the switches. Then for some strange reason the admin interface of the srw2048 plugged into the non-root 6509 stops responding. If I disable either the interface its plugged into on the 6509 or the other srw2048 everything starts working again. Sometimes it responds after many failures for no apparent reason. I looked into the mac-address table on the 6509's and they are conflicting, pointing to each other for the mac-address of the broken srw2048. When I clear the mac-table the admin port comes back for about 5 seconds then again goes dark. When reviewing mac-table on the 6509's they are back to pointing to each other. The odd thing (although I haven't confirmed this completely) is that hosts placed into vlan 2 on that same srw2048 seem to work fine. If there was an STP loop or something misconfigured, I would expect it to effect any host in vlan 2 or the other vlan's for that matter on the srw2048 that stops responding. Alas, I am stuck because I need to manage this switch remotely. My only thought is that for some reason even when the STP status is blocked the broken srw2048 is still sending out arp's of its admin interface and bypassing the STP protocol. I have no way to confirm this, but maybe someone has an idea as to what I'm doing wrong, or otherwise offer a solution. For now, I simply removed vlan 2 from the 6509 that the broken srw2048 is plugged into and everything seems fine.
My apologies for such a long post, but this is somewhat complicated. Thanks in advance for any info.
-Geoff
Message Edited by gmyers on 08-19-2008 10:35 PMTo follow up, I had a ticket open with Linksys about this for about 3 months with no resolution. I submitted packet captures, stp outputs, etc and no luck. I gave up and basically had to revert to a manual failover for redundancy. It's no perfect or fast, but it works every time.
Unless linksys issues a firmware upgrade with this as a fix, I doubt we will be able to ever resolve this on our own. -
Can't get past configuration utility to find MAC address
How do I locate my iPod Touch's MAC address prior to completing the configuration utility so that I can add the address to a router's MAC filtering list? It doesn't appear that I can do anything with the iPod unless I first go through the config process...but if I don't have the MAC address, I can't connect to my WiFi.
Any suggestions would be appreciated.

With iOS 5, you can setup the iPod via wifi without connecting the iPod to a computer. However, you have connect to wifi to do that. The poster is trying to set it via wifi but can't since he does not know the MAC address to add to his router so the iPod can connect to wifi. That is why I told him to set up via USB and iTunes.
cliftonfromrichmond wrote:
Well, you don't need to add the iPod's MAC address to the router filter table until AFTER you set up the iPod.
Think about it: To set up a new iPod you use the USB/Docking cable to connect the device to a computer that is running iTunes so you can use iTunes to set the device up. During the setup process you are using the computer's network connection to transfer data to and from Apple.
After the device is set up you can retireve the MAC address.
FYI: My home network is set up with MAC filtering....
OK, fine. And what are the chances his new iPod is not running iOS5? (HINT: He didn't add an iOS tag to his post...) And if I read his post correctly this is a NEW iPod because he has to run through the configuration utility.
I'd say that based on a recent thread about a replacement iPod not running iOS5, I'd say the odds are pretty darned good that the OP's iPod is not running iOS5. With that being said, he cannot setup his iPod over a wireless connection which negates the necessity to retrieve said MAC address. He must connect his iPod to a computer. -
DNS / BIND - Can I configure primary and standby forwarders?
Hi all,
I have on Solaris 10 (x86) a DNS server (BIND 9.3.6-P1) that relies exclusively on two “forwarders”: 155.28.144.13and 154.23.134.32.
The configuration is as follow:
# cat /etc/named.conf
acl "CSClan" { 192.168.4.0/24; 192.168.7.0/24; }; //CSC internal LAN ip address range
options {
directory "/var/named";
forward only;
forwarders {
155.28.144.13;
154.23.134.32;
allow-query { "localnets"; };
# cat /etc/resolv.conf
nameserver 127.0.0.1
When I check with snoop, I can see requests sometimes to one forwarder, sometimes to the other.
Is it possible to configure DNS to use primarily one forwarder?
Thanks in advance for your support.

Base Radio Mac and SSID MAC addresses
I am looking for a way to obtain the SSID mac addresses from a report or other method. We have clients attaching to an SSID that show a MAC address that I am positive is the MAC of the SSID (based off the physical MAC of the Radio) but I cannot find it either in reports in WCS or on the controller.
Thanks!try the following command via the CLI
show dot11 bssid

BE 5K CUCM and CUC Mac-Address registering license
Hi All,
I am really confused for registering CUC license to which mac-address. (CUCM or CUC)
I have CUCM be 5k on Server 7828 both CUCM and CUC is installed on same server. For CUCM i got the mac address from show status, but how about registering the license to CUC it should be registered on same CUCM Mac address or CUC has different mac-address.
I uploaded the licenses in CUCM and need to upload the license in CUC.
Thank you all in advance.

CNA 5.5 and show mac address-table
When trying to Monitor/Search for MAC address in C2960 network I got an error reply that a CLI command is not supported. Analyzing network traffic shows that CNA 5.5 is issueing 'show mac-address-table' command but the latest Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(55)SE does not support 'show mac-address-table' anymore but does support 'show mac address-table' command. How can I change the command for showing mac address tables in CNA 5.5?
M.hi john,
the show mac-address-table command should be valid.
check if you've got MAC learning enabled on the ASA interface using show mac-learn command.
edit: could you post show firewall? the above command works on transparent firewall only. -
