Cisco Switching/Routing :: UDP Port 10000 And IPv6 Ports Listening

Aug 30, 2012

I've several production Catalyst switches that are listening on the same IPv4 and IPv6 ports. The problem is I don't want the switches listening on the IPv6 ports.[code] How to shut down these listening ports?I also have a few production switches listening on UDP/10000 and I cannot determine why this port is listening. [code] I've seen where UDP/10000 is Network Data Management Protocol and is related to Storage networks ###, but I've also seen where UDP/10000 is the default port for IPSEC data.I don't believe UDP/10000 is related to either NDMP or IPSEC data, though I could be very wrong.

Cisco Switching/Routing :: Get Traffic From 192.168.1.33 On UDP Ports 10000-20000 And 5222?

Cisco Switching/Routing :: SG300-10 See All Traffic From All Connected Devices On Any Port / Where To Connect Listening Device

Dec 20, 2012

In my LAN environment, I'm using two cisco SG300-10 switches. Both switches are connected by GE10 on both switches, where both ports are set to trunk.Now on all ports 1-9 on both switches, I'm having client computers attached. So I set ports 1-9 to "access" mode.All interfaces on any switch is left in default vlan.
 
Is it normal that I see all traffic from all connected devices on any port where I connect a listening device?What I'd like to achieve is, that only traffic that is meant for a specific workstation is actually forwarded to this workstation. By now it seems that I get all the traffic from everybody.

Cisco Firewall :: ASA 5505 Appears To Be Listening On All TCP Ports?

Aug 7, 2011

When I do an NMAP scan against my ASA 5505 on it's internal interface's IP address, it appears to be listening on all TCP ports.  If I do it from across a VPN tunnel, the ports show as open according to NMAP, if I do the scan from the local subnet they show up as unknown. I'm running 8.0.4 code on this ASA.

Cisco Switching/Routing :: 3750X - Adding Ports To Existing Port-channel

Jan 29, 2013

I need to tear down an existing port-channel on a 3750X running c3750e-universalk9-mz.150-1.SE3.bin. This port channel is currently down down. It has three ports in it that will be added one each to three existing port-channels, I am assuming as long as the "channel-group" command is exactly the same as it is on the three existing port-channels I should be ok just adding the new port. One point to note is that the three existing port-channels all have three ports so this will be adding the fourth port to each port-channel. I know after reading that it is a best practice for load balancing to use either 2, 4, or 8 ports for a port-channel. Also what is the command to see all ports that are in a port channel?

Cisco :: Spanning-tree Every Port Go Into Listening / Learning State

Apr 4, 2012

Ages ago I was shadowing someone making a change on the network. I cannot remember which spanning tree version was running and cannot remember the config of any port either. What I do remember is that every switch port on the 2960 switch went orange and an outage occured, where the ports went into listening / learning mode. I assume that the STP was just the default ieee 802.1D.

Cisco Switching/Routing :: Configuring 1941 With 8 Port EHWic Switch Module And Onboard GE Ports In Single LAN?

Jul 1, 2012

Can you configure a Cisco 1941 to use an 8 port EHWic module and the 2 onboard GE ports in a single LAN?

I've discovered you can't have the on GE ports associated with a VLan, and I'm when I've previously researched for a solution, bridging was mentioned but I cannot seem to get it to work (or completely understand it)The reason I would like to use all 10 ports on for the LAN is becuase I have 10 devices I need to connect to the 1941?

Cisco Switching/Routing :: IPv6 HSRP Implementation On IOS-XR 4.2.1

I'm looking to try and implement ipv6 HSRP on a series of IOS-XR Routers running 4.2.1 following on from successfully setting up IPv6 HSRP on a few cat6509s on VLAN Interfaces in other parts of the network. I have entered the "router hsrp" configuration menu and gone into the interface in question that I'm looking to setup with IPv6 HSRP. Unfortunately, there version 2 or address-family ipv6 commands are not available.

Cisco Switching/Routing :: Catalyst 2960S IOS 15.0.2 IPv6 Don't Work

Aug 8, 2012

Just I have upgraded some 2960S to IOS 15.0(2)SE from a IOS 15.0(1)SE3 and the catalyst don't switch any IPv6 traffic. Don't work any RA and also don't work any unicast IPv6 traffic from any interface. I can see some references to IPv6 changes in the FHS (First Hop Security) in the Release Notes, but no any reference to changes in the configuration.
 
The switches don't have any IPv6 specific configuration and the sdm is the default templata. Returning to 15.0(1)SE3 everything work ok.
 
On Catalyst 2960, and 3560E this IOS version seem to work fine with IPv6.

Linksys Wireless Router :: EA3500 Ethernet Ports Do Not Support Ipv6?

May 29, 2012

Region : Ireland
Model : TL-MR3420
Hardware Version : V2
Firmware Version :
ISP :

I have my router updated with the latest firmware and I'm pretty sure all the settings are correct but I'm only getting a max transfer rate of 144Mbps. I know this because I use InSSIDer 3 to analyse my wifi network etc. I stream movies over my network and while DVD quality movies play fine, HD movies tend to freeze and buffer a lot. I have the router's channel width set to 40Mhz, so I know that's not the problem. Strangely, I also use a Netgear wifi extender with the MR3420 and it's max rate is 300Mbps.

Cisco Switching/Routing :: IPv6 Filtering / Policing On 2960 Switch?

Jan 3, 2012

Trying to control capacity utilization for guest users connecting to a 2960 switch. No problem for IPv4 users, but IPv6 is giving me fits. What I've found out by trial and error so far implies that there is just enough IPv6 smarts in a WS-C2960-24TT-L running c2960-lanbasek9-mz.150-1.SE to make it impossible to control IPv6 traffic. Blocking IPv6 would be sufficient short term, but MAC filtering on type 0x86DD does not appear to work either. Here are the results I've gotten so far:
 
What "works":

*  Protocol ipv6 or an IPv6 ACL in a class map.

* Using a class map referencing ipv6 protocol or an ipv6 ACL in a policy map.

* IPv4 inbound filters and policing.

* Blocking of IPv4 traffic by a MAC ACL blocking type 0x0800 (IPv4) - note that the docs explicitly state that MAC filters do NOT filter IP traffic, except for on this box on this release they do.
 
What does not work:
 
* Applying a policy map referencing a class map referencing protocol ipv6 or an IPv6 ACL to an interface. The service policy is accepted by the parser, but is not inserted into the running configuration.

* "class-default" in a policy map only matches IPv4 traffic, not all other traffic.

* Blocking of IPv6 traffic by a MAC ACL blocking type 0X86DD. No problem applying the access-group to the interface, it just doesn't do anything.
 
I am aware that this box is not supposed to support IPv6 other than for multicast, but as implemented, this is a hole an abuser could drive a MAC truck through.
 
My questions:
 
Is this situation unique to this particular 2960 switch or SW release (I also tried 12.2(58)SE2) or does it afflict all 2960's running LANbase?
 
Assuming the answers to the first two question are negative, what is the minimum requirement to get working IPv6 policing in an edge switch?

Cisco Switching/Routing :: 6509 Static MAC Address Entry And MS NLB / IPv6

May 23, 2012

I have seen other discussions regarding Static MAC address entries on IPv4, but what of IPv6?We have MS NLB solutions and they are working fine. We have Cisco 6509/6504, Version 12.2(33)SXI5
 
But then we have a new one for a new ActiveDirectory solution, and on those networks we have implemented IPv6.
 
How is Static MAC address entries and MS NLB solved in IPv6 (i.e arp ip.ip.ip.ip mac.mac.mac ARPA gi1/1). I can't seem to find much examples or documentation on this? Is it replaced with another function?The reason I ask is twofold.

1. I really want to know

2. The NLB cluster seem to drop IPv6 traffic at even intervals, witch seems to correspond with NLB transition.

Cisco Switching/Routing :: IPv6 DHCP Preferred Lifetime (Cat3750X)

There are two kinds of time for assinging IPv6 address from DHCP server.Actaully Catalyst 3750X can do this role. however I am not sure about the difference between Valid lifetime and preferred lifetime.In my understanding the valide lifetime is total lifetime for using the assigned IPv6 address but the prefered lifetime when the assinged IPv6 address is expired at the prefered lifetime then the device may generate extended request or something right?

Cisco :: W2K8 R2 - LMS 4.2 Maximum Records In Syslog Report Is 10000

Jul 31, 2012

LMS 4.2.1 W2K8 R2
 
I seem to be unable to generate a syslog report that contains > 10,000 records.  And I don't mean with run type immediate either.  I am scheduling them to run at the next 5 minute interval (incidentally, why not have an option that just says "run in background now"?)
 
I am facing an issue where a bunch of errors are being generated by a voice gateway and I want to determine when the problem started.  My syslog contains 7 days of records.  If I schedule a report to give me all syslog records for the last 1 week (or 7 days I have tried it both ways) for all devices at that location I get 10,000 records, and they are all for the current date.  If I schedule a report and select a date range in the past, I get records within that date range, but only 10,000.
