Furthermore, static DHCP ip addresses get routed wrong after 3-4 days running time.
Any ideas?
Hello plier0001,
debug arp all and check the output.
Have you rebooted?

Delete preposted budget entry document
Hi Guru's
I am failing to delete preposted budget entry document, if i use transaction code FMBB to delete preposted document the delete functionality is greyed out under document. Is there anyother way to delete the preposted budget documents.
Thank You in advance.
AlfredI don't think this is an authorization issue. I think that the budget entry is posted and therefore cannot be deleted, if you can undo the posted budget entry, then you will be able to delete it.
In the Document Overview window, click on a preposted document to select it. Click on Document on the Menu Bar and then choose Undo. An undone document cannot be recalled. Instead, a new one must be created.

Q: What is the maximum number of ARP entries (IPv4) and ND entries (IPv6) supported in Aruba controllers?
A: The maximum number of static ARP entries supported is about 2048 for M3/72xx/70xx platforms.
The maximum number of static ARP entries supported is about 128 for 6xx platforms.
The maximum number of static ND entries supported is about 2048 for M3/72xx/70xx platforms.
The maximum number of static ND entries supported is about 128 for 6xx platforms.a)It depends upon software level. b) 16,000 per card, With release 9.3:

802.1x router loses ARP entry
Firs of all, Hello All. In new to this community.
A have a strange problem i want to share with you. Possibly a bug but maybe it is me who does something wrong.
My network looks like this:
[RADIUS] --- [C881] --- [SG200 Switch] ---[WinXP]
One of SG200 interfaces is set as a Supplicant ant it authenticates in RADIUS (FreeRADIUS) server via C881 router. WinXP and other PC clients authenticate in RADIUS via SG200.
Now: Authentication works perfectly. Ports open as they're supposed to. I'm able to reach RADIUS from SG200 and vice versa but there is a problem with WinXP. When i connect it to SG200 it authenticates, port opens and I'm able to reach RADIUS or any host on the left hand side but only for 300 seconds. After that period of time C881 looses WinXP from its ARP table and any communication fails. I cant even reach C881's interface facing SG200. Then i type:
c881(config-if)#dot1x port-control force-authorized
C881 learns WinXP's MAC and IP again and all gets back to normal. When I type
c881(config-if)#dot1x port-control auto
after 300 seconds C881 forgets WinXP again and communication brakes down.
How is it possible that a router forgets MAC of host its continuously "talking" with?
Have you ever seen this kind of behaviour? I tried with two other software revisions on C881 and resoult is always the same. Bug or feature?Hi.
Are you sending the session-attribute from the free radius server?
To be honest im not sure what you mean, but i have strong suspicion that my problem has nothing with freeradius.
Host authentication works perfectly. When i connect WinXP directly to routers switch ports everything works fine. Either the switch itself has a connection to the router all the time - even when WinXP and C881 dont see each other.
Furthermore - All ports are authenticated and open all the time, its' state doesn't change. Reauthentiction is turned off.
When the problem occurs i see no traffic to radius server. hre is how it looks:
When i connect WinXP to the switch it works at the begining.
I check ARP table on the router - WinXP is there.
I periodically check ARP table and after ap. 300 seconds (default arp entry timeout) WinXP disappears and communication brakes down.
Additionally when i change ARP timeout value to shorter or longer communication breaks earlier or later respectivly -
Static Arp Entry for Exchange 2010
Hello All,
I was hoping someone could assist with an issue that our Exchange team are having, specifically with replication traffic traversing our DC to DR site.
The infrastructure consists of a Layer 3 data centre and a disaster recovery site, so essentially its a live/backup environment. Both the DC and DR site are connected with a LES using routed interfaces.
The Exchange cluster at the DC is associated with the following subnets:
MAPI - 10.1.30.X
Replication: 10.1.230.X
DR site has the following subnets associated with the exhange cluster :
MAPI - 192.168.4.X
Replication - 192.168.230.X
When an attempt is made to create a database/mailbox on an exchange server at the DC and copy it using the replication subnet source: 10.1.230.X to destination subnet: 192.168.230.X, the copy process fails.
Replication traffic in general going from DC to DR or vice-versa is subject to constant problems and seems unreliable. Our exchange team have to manually copy mailboxes from one cluster to the other using Windows explorer which works fine.
The Exchange cluster at both sites reside within a VMWare ESX enclosure and connect to Cisco 6500 switches. Would the Cisco switches require a static arp entry for their respective Exchange clusters, which should be configured on each switch? If this was missing could this be the root cause of the replication problems we're experiencing? Or does this depend on whether the exchange cluster is using NLB Unicast or Multicast mode?
Any assistance would be most appreciated.
Regards,
JamieJamie,
Have a look at this link:-
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a07203.shtml
It depends on how the team NLB is set up.
You may need static mac & static arp as well as disabling igmp snooping if multicasting is bein used.

Alex.

On my 3850 (running 3.3.1) i have 1600+ entries in the arp table for a given vlan but I'm not acting as the gateway for the devices connecting to it (i'm trunked to the core which is acting as the gateway but I do have ip routing enabled on my 3850). I've put the nmsp attachment suppress command on all physical interfaces to resolve another issue I was having.
Is having all these arp entries expected behavior? I've tried to delete 1 ip in the table which I knew wasn't valid but my switch seems to ignore it as the entry is still there.
The reason I ask was due to a small unicast flooding issue I seemed to have (since gone away). I was told it may have been due to the switch having an arp entry for a mac addresses it didn't know and hence was flooding the switch. The person was surprised to see so many arp entries given i wasn't a gateway for this vlan.
ThanksHi,
If you issue "show running config all" command you can see all configuration lines of this switch including the default settings. Here is an example for one of the vlan interface configuration. As you can see "proxy-arp" is enabled globally & interface level by default.

This post explain "proxy-arp" behaviour well.
http://www.cisco.com/c/en/us/support/docs/ip/dynamic-address-allocation-resolution/13718-5.html
In your case all the SVI defined & end host gets default-gateway IP correctly, there is no need for "proxy-arp" enabled on SVI. You can safely disable it (globally or interface level) and check if that help to mitigate your arp cache issue.
3850-2(config)#ip arp proxy disable
or
3850-2(config)#int vlan 1410
3850-2(config-if)#no ip proxy-arp

Telstra Update to my Modem has deleted Static ARP table
The latest automatic update to my Telstra Technicolor modem has caused my Static ARP table to be deleted. Furthermore, the update seems to have removed the ability to TELNET into the modem via command line, so I simply cannot re-create the static ARP table. I had previously mapped my home server's IP address to its MAC address through a static ARP entry. Doing so allowed me to remotely wake up my server when outside of my home network (Wake-On-LAN). Because of the aforementioned update to the modem, having deleted the static ARP table and removed my ability to log-in to it via Telnet - I can no longer remotely wake up my server. Pretty annoyed with Telstra right now. Waking my server from outside my home was something I would do almost daily in support of my business (details irrelevant).
Thanks. That is my back-up plan. I was hoping to avoid making an unnecessary purchase, plus the annoyance of then setting-up up my new modem with all my specific network configuration. Like I said, yesterday all was fine. Today, thanks to Telstra's update, I don't have the functionality I had previously and I am now facing the reality of having to fork out my hard-earned money to overcome this Telstra-initiated limitation.

How to delete duplicate contact entries in iCloud?
Dear Members,
I am searching for a way to delete multiple duplicate entries in my iCloud accound. I have been unable to find a solution to this except to manually delete each one individually, one-at-a-time. Any help would be greatly appreciated.
Also, if there happens to be of a way to delete all of my contacts and start from scratch, I would like to know a solution for this as well.
Thank you in advance for your time. Anyone that can point me in the right direction or provide me with a solution, I will be very grateful.
Regards,
fivanajThanks for the suggestion, Barney-15E. FYI I am not running both iCal and Calendar. Just Calendar. Me bad for using the old name and new name interchangeably.
Tackling the iMac problem: In iCloud network preferences, I unchecked Safari then soon after rechecked it, and your suggestion appears to have worked: a bookmark recently added on one of the other devices appeared in the iMac Safari bookmarks. So far so good.
Did the same thing with contacts. The iMac took a couple of hours to restore the sync setting, but it finally completed the task. The computer was laboring so I rebooted. Then I opened the contacts application and saw the spinning grey bars next to the "iCloud" heading above my list of contact groups. Some time later the spinning lines were replaced by an exclamation point. I clicked on it and got the message that the operation could not be completed because of a "CoreDAVErrorDomain error 1..". Subsequently, after much spinning of the line wheel, I have gotten either the exclamation point with the CoreDAV message or a lightning bolt icon. Whether exclamation point or lightning bolt, clicking on it provokes a long period of the spinning line wheel. And looking at some telltale contact discrepancies between the iMac and the other machines, nothing seems to have changed in terms of merging the discrepancies.
Searching for the error message in the support community, I see this has happened to others, and they have had some success in following a list of steps starting with archiving the contacts, which I have done. Don't think I fully follow the other steps, nor am I sure they apply to my situation. -

Deletion of table entries(without maintenance view) in production
Hi Sap All.
here i have got a task to change the data type of one particular field and to delete all the table entries of this table in production.
so in Dev I have tired with z program saved in local object (DELETE FROM Table).
i just want to know how i can delete all the entries of table in production.
regards.
VarmaHello,
You can also use transaction SE14.
Start SE14
Enter the table name
Select the radio button "Delete data".
Push the button "Activate and adjust database".
This will drop your table in the DB and recreate it as well as all related indexes.
Indexes are not impacted when you do a regular DELETE statement unless you rebuild your indexes.
Of course you can only do this if data can be deleted for a specific table in ALL clients.

How to setup a static multicast ARP entry with Cisco SF300-08?
We're running a cluster in multicast mode as a loadbalancer.
We have Cisco SF300-08 and when we adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.
So how to setup a static multicast in Cisco SF300 or maybe someone know other solution to setup multicastes mode in Cisco SF300.Hi, Tom!
We have two watchguard xtm505(cluster active-active) in our network. Watchguard interfaces have one ip and one mac adresses. IP 192.168.111.1(Unicast) and MAC 01:00:5e:02:02:03(multicast). Cisco SF300 is router to outside networks(to internet). Cisco IP adresss is 192.168.111.254. There are another some hosts in this network.
Ping from hosts to 192.168.111.254 works well. Ping from hosts to 192.168.111.1 works well too. But there is no ping from watchguard cluster(192.168.111.1) to Cisco(192.168.111.254). And there is no routing to internet
This is well-known situation. We need to do following(example for cisco 3750):
1. Start the Cisco 3750 command line interface.
2. Add a static ARP entry for the multicast MAC address of the FireCluster interface.
Type this command:
arp arpa
For this example, type:
arp 192.168.111.1 01:00:5e:02:02:03 arpa
3. Add an entry to the MAC address table.
Type this command:
mac-address-table static vlan interface <#>
For this example, type:
mac-address-table static 01:00:5e:02:02:03 vlan 1 interface gi1/0/11
But we can't add arp entry on Cisco SF300. CLI tells us "MAC address illegal"!
We tried enable igmp snooping, but is not helps.
Could you tell more detailed about MAC groups? -
