Cisco Switching/Routing :: No VTP 3 Possible For 2960C Compact Switches?
Mar 14, 2012
I was rather surprised today to discover that the latest IOS available for the 2960-C switches is 12.2 (55). Other similar switches, like the 2960S range are using IOS 12.2 (58) or 15.0.1-SE2. This doesn't sound like the end of the world at first, but 12.2 (55) does not include VTP 3, which is a major problem if you are using the compact switch within a large modern deployment.
Am I correct about the version?Is there any way to deploy VTP 3 to this switch?Is Cisco planning to issue modern IOS releases for this switch?
Is it possible to do dot1q-tunneling on the new Cisco Calalyst 2960 Compact series switches? I know that the 3560 series support it, but im unable to find any information about the 2960C series, personally i doubt it as the standard 2960 series don't support it.
I just read the Removing and Installing CompactFlash Memory Cards in Cisco 2800 Series Routers instructions and there was nothing said regading powering down the router. Are these CompactFlash cards hot swappable??
If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?
If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?
I have a 3725 router and would like to upgrade the slot:0 compact flash to a higher capacity. My question is, I can just pick up a 4GB compact flash card from walmart, or do I have to have a card from Cisco?
We have a pair of N7K distribution switches connected to a pair of N7K Aggregation switches.We run vPC on both pairs of n7k's.
-n7k-d1 has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC1) -n7k-d2 also has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC2)
My problem is that Spanning-Tree is blocking PC2 and all traffic from n7k-d2 is traversing the Peer-Link before reaching the Aggregation layer. Is this the best design for connecting two pairs of n7k's with vPC or if a better design would be to connect all 4 links into the same Port-Channel and vPC?

Is there reason why WS-C3560C-8PC-S and WS-C3560C-12PC-S is not supported in Cisco Network Assistent? According to the data sheets for these switches CNA should be supported. I saw another forum post stating that the Gigabit versions has been added to the supported list as of version 5.7."The Cisco Catalyst 3560-C and 2960-C Series compact switches offer both the traditional Cisco CLI for detailed configuration and Cisco Network Assistant software, a PC-based tool for quick configuration based on preset templates."
I need to upgrade the compact flash memory on a 2821 router from 64 to 128, upgrade the ios, and re-script the router. So I'm wondering what is the correct sequence? With the router powered on, do i eject the existing flash, and install the new one or do I power down the router? Once the memory has been increased, then i can upload the new ios?
I am attempting to install a 512 MB Cisco COmpact Flash for an ASA 5520. We have inserted the compact flash but when we do a DIR, it does not show. even as an unformatted device.
What do we need to do to make this a usable CF? Do I just need to reload the ASA or do I need to format the CF. It has been inserted into the slot in the back of the ASA 5520 and we have ensured that is had been seated properly.
I have just brought a brand new laptop which has WiFi init i have taken it across the road from my home to my brothers to get connection it shows the networks and signals but after putting in mt phase word and password it keeps asking me for a security network key i don't any clue where this is or how to obtain this. I would have thought because i have WiFi ill get connected straight away specially with the signals coming thru strong.
Why Cisco implements so much switching capacity in their switches Obviously,16 Gbps of permutation performance is too much for the 8,8 Gbits (24*200+2*2000) needed by ports so why they put so many bandwidth?
I'm trying to configure intervlan routing between a cisco 2801 router and HP/Amer switches. Using int fa0/1 and subinterfaces I was sure I had it configured correctly, but I cannot ping the default gateways when I place a host in a particular vlan. Below is what I have configured.
HP switch - port 9 connects to fa0/1 on 2801 ip default-gateway 10.1.100.1 trunk 9 Trk1 trunk trunk 10 Trk2 trunk - to another switch
I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)
I have a simple design with 3750. I configured a route-map which define a next hop. I defined this route-map on a policy on a vlan interface.When I test some ping and a debug ip policy and it seems that my policy never match.Is there any mechanism that prevent the switch from using PBR? I think of CEF .

Is L3 ip routing on by default in 3550s? If so is the "ip routing" command visible in the config file? If no - I assume that one would enable L3 routing with that config command.In general terms are there any IOS devices where ip routing is enabled and one would not see the "ip routing" command in config. I.E. if that command is not visible in the config could you assume there is no L3 capablity in that device?
CiscoSwitch1(4506) has 3 VLANs(12,13,14) and Switch2(4948) has 3 different VLANs(22,23,24) and IP routing has been enabled in both switches with SVI interfaces for each vlan. intervlan routing is works fine.Now there is a requirement to connect these switches together. Vlan 12 on the Cisco switch 4506 has to be made available from vlan 22 from Switch2(4948). basically Vlan 12 is having a multicast source (225.0.0.0 & 226.0.0.0) which should be accessabile from vlan 22 of cisco switch 4948.I got 2 ideas
1) Create a trunk between these switches and configure L2 vlan(12) in cisco 4948...i know theoritically it should work but what my concern is Ip routing enabled in both switches will it create any issues? is it a gud solution to this requirement?
2) Create a separate IP network on the ports connecting to both switches and set up routes to the networks.ex- console(config)#ip route 192.168.10.10 255.255.255.0 192.168.20.1.
I am facing this particular issue while providing Cisco unified Wireless solution to the customer. We are having CAPWAP 1252 APs controlled by WLC.
Scenario: 50 persons sitting in a hall with closely packed chairs using wireless simultaneously. Wireless access provided by patch antenna at a height of 11m from the user. As one AP can server 25 users, 2 APs are placed with antenna directions facing the compact users. Each users gets very good signal from these two APs.
Whether there will be serious interference and client association issues in this scenario? once one AP associates 25 clients, whether other 25 clients associate completely to other AP?
I have a small campus network using 3750 stackable switches and a 3725 router (see diagram below). Currently the 3725 router is handling inter-vlan routing for the campus and it looks like it's not able to handle the amount of traffic we're pushing. The router CPU sometimes hits above 90% due traffic load. What I would like to accomplish is move L3 process over to the 3750 MDF stack and the IDF1 stack. I am thinking creating SVI's on both MDF stack and IDF1 stack, run HSRP between the two stacks and may be do load balance traffic between the two stack as well.
Is there a way to load a spare compact flash with a running-config, ASA IOS, & ASDM software via card reader? I need to load another flash card with all of the settings necessary for normal operation. This "spare" card will replace the flash that is currently in use. The reason for the replacement is capacity and because of changes made to the running-config. The "in-use" card is 256MB, the "spare" one is 512MB. Also, the new card will have a few changes made to the running-config, so it will, in essence, be a reload.
I have a card reader for the compact flash cards. If there is a way to load up this new card using the card reader, without monkeying with the firewall, I would prefer that. Like I said in the previous paragraph, this new flash card will replace the other one, once it's ready.
Hardware: ASA 5510 CF: 256MB (wanting to upgrade to the new 512MB card) ASA IOS: 8.4
I have two C2960 switches which have the management VLAN for other switches. These two switches are connected with each other via portchannel. Now the mgmt0 of few switches is connected to switch 1 and few other connect to switch 2.I have also connected the mgmt0 of switch 1 to an access port of switch 2 and vice versa.However in this set-up I am unable to reach switch1 via the mgmt0 IP address. However I can reach the mgmt0 Ip address of switch 2.I can also reach switch 1 and 2 via their int vlan IP.Has some one else experienced this and is their any specific reason why mgmt 0 IP address of switch 1 is not reachable.I have tried doing similar set-up on C3750, but have acheived same result i.e. I am unable to reach mgmt0 of switch 1.
I have a server windows 2008 that I would like to have a nic teaming configuration, the server has two nics, each nic is connected to a different switch. One is connected to cisco 2960 and the other is connected to cisco 2950. I have read here in forums about nic teaming but using the same switch. I have not found using different switch. Is this possible?
We have 3 layer LAN architecture, layer 1 of 6500(IP routing), layer 2 of 4500(L2 switch only), layer 3 of 2960(L2 Switch)In a Single (2960 and 4500) Switch Port Avaya IP phone and PC are connected.Now, the requirement is that, Qos need to be configured for Voice traffic and Data traffic should be in default class of service.We plan to use COS value in Switch 4500 and 2960. We made a sample configuration as below
### For 4500 Switch class-map match-all VOIP-Access-2MB match cos 3 5 class-map match-all VOIP-Uplink-20MB match cos 3 5
[code].....
check these configurations are correct as per standard and if there is any other method of configuration?What need to be configured in L3 Switch(6500)??In 2960, it doesn't support ingress QoS, what impact it will make when compare to 4500? do users experiance any difference?
I have one 3550 switch and i upgraded from 12.1 to 12.2(44)SE . But "tclsh" command is not enabled on this version. As per Cisco, 12.2(25)S is enough to enable TCL interpreter.
I've upgraded a 6509 switches wich are running in VSS, from IOS 12.2 (33)SHI1 to 12.2 (33)SHI5. After that I'm facing the folowing log messages periodically. [code] I know that this is a diagnostic result from TestUnusedPortLoopback feature. But this interface is disabled (shutdown).
