i'm going to change all of my old switches in CED with new ones 2960-S. I was reading about Flexstack Cisco technology is able to group from 2 up to 4 switches into one logical switch.I just have a doubt about my environment. Master switch in stack replaces the same configuration to all slaves switch into cluster. But if i would have different access vlan on different switch how could i proceed?
View 4 RepliesI would like to use flexstack to stack two Cisco 2960S 48 Port switches (2960S-48TD-L) for redundancy. Each switch will have a single 10G uplink into our Nexus 7K. One switch in the stack will terminate to linecard 6 (N7K-F248XP-25) and the other switch will terminate to linecard 7 (N7K-F248XP-25). My question is how many flexstack cables are needed? Do I need only one cable or do I need two to connect the two 2960s ?

View 2 Replies View RelatedI am trying to configure etherchannel on 2 2960S connected by a flexstack with 2 ports g1/0/52 and g2/0/52 on each 2960.
these switch are connected to a CAT4500, I know that I can only use LACP because of cross-stack but when I force the switch to use LACP witch channel-group 2 Mode active the switch do this :
%With PAgP enabled, all ports in the Channel should belong to the same switchCommand rejected (Port-channel2, Gi1/0/52): Invalid etherchnl mode
% Range command terminated because it failed on GigabitEthernet1/0/52
I don't know how to bundle the 2 ports on the 2960 stack. each time I use : channel-group 2 mode on there is no error
but the switch do this :
*Mar 1 00:45:32.290: %EC-5-CANNOT_BUNDLE2: Gi2/0/52 is not compatible with Po2 and will be suspended (trunk mode of Gi2/0/52 is dynamic, Po2 is trunk)

I have been trying to make a stack with two 2960S. They have the same IOS but they behave as they were not connected.One is in production and I am attaching a brand new one to it; in the one that is in production I get these 2 messages:
FlexStack Module SmartChip Authentication Failed.I tried switching the modules and the outcome is the same, so I think the modules are ok.What to you recommend, is there a way to bypass this authentication?
How can I edit a static interface IP address? I don't seem to be able to edit the static IP address for my switch. How do I go about changing it? As you can see the IP Address field is not editable.
I have also upgrade to the latest firmware and I cannot figure out how to edit it via that as well.
I just purchased 2 SF-300 48 port units for 2 customers. I want to be able to remotely manage them over the Internet with my browser. BUT, customer sites already use port 80 for web servers. So, how do I configure this switch to use some other port than 80?
I called support, and much to my surprise he said it cannot be changed. How bizarre that a device with many hundreds of configuration settings does not have one of the most basic settings...
At one customer site I can configure port forwarding and translation to get around this problem, but the other site's router does not offer port translation..
I want to know how am i do to change the Vlan1`s IP address because the actual ip will be used in another vlan. Actually i haver 10 vlans in L3 mode (routing) implemented in it.

We've got a SG200-18 switch that is to be used as a workgroup switch in our environment (SW Version 1.1.1.8). Working with CLI on big and mid-range Cisco-gear over the past two decades I'm having a hard time figuring out the following on the SG200:
o) I want to change the Management-VLAN from the default "1" to the management-VLAN used in our environment. Sure enough I created that vlan in the SG200-config, however when it comes to assigning the management-IP and VLAN for the management interface in the corresponding pulldown under "IPv4 interface -> Management VLAN" the only thing selectable is the default "1". (see screenshots enclosed)So how do I set a management VLAN different from 1?
o) How do I enable telnet/ssh-access to the SG200-18 - I'd be far more comfortable with a CLI-environment?
My SF300-24 switch has been working 100% as a backup switch for a client of mine. At my clients premises it was running 3 Vlan's and doing inter VLAN routing. When my client received their original switch back, I obviously brought my SF300-24 back to the workshop, reset it back to Factory defaults and tried to do a fresh installation on it. I can not get it to change from Layer 2 to Layer 3! I installed the latest firmware but still no go.
Everything works a 100% via the console, but when I go to the System Mode menu and try and edit it, it justs sits at layer 2 and will not chage to layer 3!
I recently purchased an SG300-10 switch. Is it possible to change the TCP port numbers for the administrative services on this device? For example, if I wanted to change the web admin port from being availble on port 80 to port 8080, or move the SSH port from 22 to 2022, how would I do this?
I've looked over the web admin interface, and the Security > TCP/UDP services option looks like what I want, but I see no way to change a service's listening port. Is this possible?
I am configuring ise to do the posture assessment. I am having avaya as my LAN and Core switches. The idea is once the user is authenticated using 802.1x then it will be moved to qurantine vlan and after it is compliant with the company's policy then it will be moved to the actual vlan. I have configured the avaya switch to accept the radius assigned vlan and also configured the 802.1x dynamic-authorization. Currently, radius assigned qurantine vlan is working but once the nac agent scan and mark the PC status as Compliant then the CoA is not happening and User is not moved to the actual vlan.
I tested the same ise authorization policy of dynamically assigning VLANs on cisco switches and it worked perfectly, but the same is not happening on avaya switch.
We've been trying to monitor the used bandwidth of our SGE2000 and SGE2010 switches with Nagios.We've been experimenting with the various OIDs and we've found the OIDs linked to the different switchports.
Though when we use SNMPWalk (to find the OIDs connected to the port) the names of the ports are all the same.
[code]....
Is there a way to change the names of these interface to unique names?We've already given unique names in the description field through the switch's GUI, but it doesn't make any difference for Nagios.
I've been taught/under the impression that vlans and stp stay in the access layer to prevent bridging loops and broadcast storms from taking down the whole network. Well I was reading about backbonefast and how it "Enables fast convergence in the networkbackbone or core layer switches after a spanning-tree topology change occurs." Now I thought that from the distribution layer up we use a routing protocol.

View 7 Replies View RelatedIf 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?
View 7 Replies View RelatedI have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
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?

View 1 Replies View RelatedWe have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each. Switch was connected to HQ Network as untagged VLAN 101. I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great. Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
I then Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.
does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?
