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 :: Login To 2950 Switch And Modify VLAN Entry On It?

Nov 3, 2011

In my lab, there are some machines that are connected using Cisco 2950 switches. Those machines belong to a VLAN.Now I need to modify the VLAN settings of the machines and as such I also need to modify the VLAN settings on the ports on the Cisco switches.
In order to do this, first I need to login to those switches, but due to a lack of knowledge transfer, I don't have the password. Is the some generic password?Second I will need to  modify the VLAN settings on each individual port. How can I do this?

Cisco :: Configure 2960g Switch Static Routing?

Jan 26, 2013

I have routing enabled, can build a static route, and go back and see it (sh ip route), but I don't know how to get the route right. I have one host (Host A) on Vlan 20 w/ dg (the vlan ip) and (Host B) on Vlan 30 w/ dg (the vlan ip). I can't ping them from any host man. I can ping the Vlans but not the host.

Cisco Switching/Routing :: How To Configure 6506 Or 2960G To Process Multicast Traffic

Aug 8, 2012

Multicasting.  The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10.  I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch.  On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10.  The 2960G switch has a workstation connected to it that needs to receive the multicasts.  How do I configure the 6506 and/or the 2960G to process the multicast traffic?

Sep 3, 2012

I am working on Multicast scenario, There is one 6513E switch one 2960 switch. Two VRF's are configured in core switch (6513) IPTV-SRV and Villa-VRF IPTV-SRV vrf has IPTV server and Villa-VRF has IPTV i.e. client.
V LAN 30 is mapped to IPTV-SRV vrf with subnet address
V LAN 12 is mapped to Villa-VRF with sub net address
I did the following configuration for VRF but its not working . i am not an expert in multicast design but seems i did most of the configs.
ip vrf IPTV-SRV
rd 30:1
mdt default
route-target export 30:1
route-target import 10:1

Cisco Switching/Routing :: Finding Switch That Supports 4096 Multicast Groups

Jul 10, 2012

Any switch that supports 4096 multicast groups?I am working on a system that includes over a dozen catalyst 2960 switches.  The customer has pointed out the 2960 switch does not satisfy the requirement to support 4096 multicast groups (even though it is more than adequate for the number of active multicast groups).  It looks like the 3560 supports more multicast groups than the 2960, but is still far less than the requirement.

Cisco Switches :: Manual Multicast ARP Entry For SG300

Jan 22, 2012

We're replacing our older catalyst switches with new SG300 family switches and have a Microsoft NLB cluster for some services that run in multicast balancer mode.
We currently do L3 routing to the network with the cluster and have the following IOS configuration line in the specific switch to let users on other subnets to access the services.
arp 03bf.0a14.01e2 ARPA
How do we replicate this using the SG300 series in L3 mode? Whenever I try to add a manual ARP entry I get an error message that says that the MAC address is not a valid unicast address?

Cisco Switching/Routing :: Static Routing With C2960G Switch

Two Cisco C2960G Switches connected with each other using an EtherChannel Trunk Ports.IOS Image has been upgraded to c2960-lanbasek9-mz. 122- 58.SE2.bin.The global command "sdm prefer lanbase-routing" has been executed to set the default template to "lanbase-routing".The global command "ip routing" has been executed to enable the ip routing.An IP route has been configured in each switch to point to each other for the static routing purpose (Please see the 2 attached configuration files) The hosts in VLAN 111 and VLAN 110 are not able to see each other even the ip static routes have been configured.May be I have misconfigured some settings but not sure what's the actual problem.

Cisco Switching/Routing :: Configure QoS On 3560 Switch?

Jun 7, 2012

configure QoS on 3560 switch i have taken the template from cisco configuration guide since we have different QoS configuration on each model.
below is the configuration :
configure terminal
mls qos
mls qos map cos-dscp 0 8 16 26 32 46 48 56
no mls qos srr-queue input cos-map                mls qos srr-queue input cos-map queue 1 threshold 2 1                mls qos srr-queue input cos-map queue 1 threshold 3 0    

Currently all the cisco phones are connected to this switch and configuration with only one vlan that is voice vlan .
1) what is the outcome of this configuration , i mean, what will be the expected output ? end of the day we need to prioritize the voice traffic but why other commands including threshold and buffers are mentioned with respectives queues , if I need to explain that what am i expecting out of this configuration ?
2) this is LAN QoS which i understood but again , do i need to configure policy-map along with class-map which is MQC on this switch ?
3) i have edge router where i have MQC already configured but confusion with this switch which is working as a Access switch .

4) I referred the cisco QoS document for the respetive model whereas we have policy-map configured on the same switch with class-map .

My understanding is if we have configured the LAN QoS , and mapped the CoS value with DSCP , we need not to have MQC.

Cisco Switching/Routing :: Configure 2940 Switch To Work With 1841?

I have a Cisco 2940 switch and a Cisco 1841 router. I want to build two different VLAN networks on the switch, which do not have to communicate one with each other, but those VLANS should communicate with the router.
I read a lot of articles, i tried to configure properly the switch and the router but i still don't get them work.
I set on the switch, the GigabitEthernet 0/1 port to Trunk port and i had to set it a native VLAN. The problem is that only from that native VLAN, i can ping the router.

Cisco Switching/Routing :: Configure 3560X Switch For ISCSI Connectivity

Mar 19, 2012

I haven't worked with infrastructure much lately but planning on replacing a Dell switch used for a small iSCSI SAN with a Cisco 3560x. Switch is sstorage ONLY, network handled through different switches. I believe I want to disable spanning tree and configure trunking for the 4 GB ports connected to the storage array. The switch is providing connectivity to SAN via multiple GB connections and then also multiple GB connections to 3 Vmware hosts.Can you look over the changes I made to config below and let me know if I am on the right track.
I also plan to add a second switch later with the 10GB modules to interconnect for redundancy (but not worried about that part for now). I do not plan on using jumbo frames.
Here are my questions

1) Is the best way to globally disable spanning tree for the switch?

2) Did I trunk the ports correctly below?

3) Should I apply any specific SmartRoles to the 4 SAN NICs (GE1-4) or to host NICs (GE13-20)?

4) Anything additional I should do to handle iSCSI data? 
Here is a copy of the config so far with my changes marked in RED.
