I've a 3750-48ps-s running ios version: c3750-advipservicesk9-mz.122-46.SE.bin
I've tried to configure ipv6 on an interface but it does not give me the option.
How do I know if my ios is IPv6 capable?
I want to upgrade the IOS version of 3750 48PS switches. these stacks are located on different building some of the them having 2 members and some have 3 members in a stack.step by step to upgrade the IOS of these switches.

I want to add 3-rd switch to it:
Switch: WS-C3750G-48PS 12.2(25)SEE3 C3750-IPSERVICESK9-M
Will this configuration work? My main concern is IOS difference?
I have 3750-48PS-S in production and would like to stack it with C3750G-48PS. Both switches are running code:
c3750-ipservicesk9-mz.122-50.SE3.bin
I am in the process of upgrading our stack of 4 switches consist of WS-C3750G-48PS. Upon reading release notes found that there are two versions of release notes 1 day apart, the one 02 Sep 2012 saying that WS-C3750-48PS is not supported in this version. Then in release next day 03 Sep 2012 that note has been removed. Which one is correct. Is it supported with my model of switch or not. Also unable to update boot path in the stack switches, "switch all" is not supported in the current IOS. Any other way to update it. Master switch has new boot path but unable to change in slaves.
View 2 Replies View RelatedWe recently connected a RPS 2300 to our switch WS-C3750G-48PS-E with IOS c3750-ipservicesk9-mz.122-53.SE2.bin.However i do not see any RPS details in the"show env" output.I believe i should get the RPS Name and its Serial and the port number in the output, but i am not finding it in the output. I did reload the switch but still couldnot get this udpated.
View 3 Replies View RelatedAt this moment (firmware 1.0.3.5) the router has no IPv6 firewall and therefore when used in a typical dual stack IPv4/IPv6 network it has no protection regarding IPv6 traffic. Hopefully this will be fixed with a firmware update before the World IPv6 Day on the 6th of June 2012.

I recently removed a catalyst 2950 switch code version: c2950-i6q4l2-mz.121-13.EA1 ?I had an ASA 5505 connected as a switchport access to the 2950 on port 44. We will call the VLAN that the ASA sits on: VLAN 404. The 2950 had a trunk to our catalyst 6509 distribution switch carrying that VLAN 404. We also have a another VLAN for computers that sits on: VLAN 129, this is a standard DHCP vlan and it accounted for the rest of the switchports. The 2950 also has this trunked to our 6509 distribution switch.
Everything was working fine with that setup.After replacing the 2950 with a 3560 we started running into problems. The 3560 was configured the same exact way as the 2950. What was happening is that computers that sat on VLAN 129 started experiencing packet loss and were unable to work. It's as though the ASA was taking over the switch.
Is there a protocol that is enabled by defult on the 3560 that would do this?
We had some problems with 3560G-48PS-S switches and PoE for our phones. IOS is 12.2(50)SE3. There were some problems after power outage. The switches didn't reboot because we have two eletric circuits. But after the problems we had no PoE on all ports.
The switches logged to following syslog message:
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi0/17: Power Controller reports power supply VDD under voltage
I can't find any informations in the error message decoder for that. But there was another thread here with quiet the same message, but another problem regarding RPS2300.
After reloading the device all works fine again. The workaround with the commands "power inline never" and "power inline auto" I didn't know till today.
Some information about that syslog message?
My guess is that there was a voltage swing and the switch powered down its supply? Is that possible?
In my office we bought 7 cisco 3750X - 48PS switches. We configured Data Stacking between those switches. We also want to configure Power Stacking between those 7 devices.
I found in the Data Sheet that we can only configure 4 devices in power stacking at a time. If it is like that how to configure the rest of 3 devices. Need configuring power stacking between those devices in a better way..
power stack cable part no we have is
CAB-SPWR-30CM
We are using WS-C3560G-48PS connected via UPS power supply. Whenever raw power supply gets fluctuates few of the IP phones (Alcatel) gets reset although switch is remain up and running. We checked the same by disconnecting the raw power supply but we didn't found any packet loss from the node which are connected through this switch. But few IP phone gets reset. What could be the reason

View 7 Replies View RelatedI have been experiencing a strange problem i have a switch stack of 3750 in which 4 switches are cascaded. there is one one switch shows PROVISIONED status when I run "show switch". i have verified the stack cable connectivity its OK.
now when i try to console that particular switch i am unable to access it as well. I tried to reboot that switch and on reboot it only shows one LED syst blink once and after that remains constant and nothing happens to other LEDS. from the back of the switch FAN is working fine.
I have configured DHCP snooping on a WS-3560G-48PS running IOS 12.2(58)SE2 ipservicesk9 variant.When I enable DHCP snooping clients don't get IP addresses, when DHCP snooping is disabled, everything works fine.I have set up a SPAN port and run a capture (attached) on the traffic. Wireshark notes the Seconds elapsed field appeared to be encoded in little-endian but only on some packets. Apart from that, I can see nothing wrong with the DHCP Offer responses from my DHCP server.Attachment config.txt contains the interesting parts of the configuration. Please note g0/32 has been set to ARP inspection trust as without working DHCP snooping it would require a static bind.Is there any way of figuring out which option can't be parsed? Is there a way to force forwarding of unparsable DHCP packets while still running DHCP snooping?
View 3 Replies View RelatedI had a strange issue yesterday when onsite installing a new access switch.Port capacity full on a two switch stack of 3750 x48 PS switches (WS-C3750- 48PS-E)- New 2960 x48 PS - WS-C2960S-48FPS-L racked, with the plan of using it just as an edge switch via SFP Stacking cable.Setup the two connecting ports with simple initial config: - switchport mode trunk- no encapsulation option on the 2960, default dot1q- dot1q set on 3750 port- no shut on both sides.Connected the SFP Stacking cable but it didnt work:- %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/0/1 is not supported
This is ok as I had a backup:- Next step tried using 2 x Short Haul SFP SX GBIC's with LC - LC OFNP 50/125 fibre patch lead - no joy- Extra backup of 2 x Long Haul SFP LX GBIC's with the same fibre patch - no joy- Checked the fibre and it was not a cross over so transmit and receive going down the same side, switchedand still would not come up.- Used Fibre as a straight through and still the same.In all cases there was no indication of any life in the connection.It is pointing to a faulty fibre patch lead but I know it has worked in the past. Could it be something to do with the config or device incompatibility? Or any setting I need to activate?
I have a c3560 that on Port 1 I can not get any device to talk to the DHCP server.Previously there was a client connected to this port however over the weekend he stated he lost connectivity.
In my troubleshooting I have connected that client to another port and now he is good to go...I connected my laptop and tried to connect to the network however I could not.I checked the logs and did not see anything that lead me to think it was having problems.
Is there another way to shut this down and hopefully start it back up without having to restart the entire switch?
After powering up a WS-C3750-48PS switch, Normal POST LED flashing of lights does not happen, instead the switch is stuck in SYST Mode on the front panel. My attempt to hold down the mode button upon powering up for 15 sec fails to reboot the switch. I cannot console to the switch. Is this switch unrecoverable? Should I RMA with TAC?

View 1 Replies View RelatedI am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]
one of our switches (WS-C2960G-24TC-L). When I try to turn on the lanbase-routing feature using sdm prefer lanbase-routing, it gives me an error (Unknown command). I tried "sdm prefer ?", and lanbase-routing wasn't there (only qos, default and dual IPv4 & IPv6). The switch is running on image C2960-LANBASEK9-M version 12.2(50)SE5.We have another switch (WS-C2960S-24TS-L), running on image C2960S-UNIVERSALK9-M version 12.2(55)SE5, and I can enable lanbase-routing feature. If I upgrade the WS-C2960G-24TC-L to version 12.2(55)SE5, will it be able to do inter-vlan routing? Or is the switch itself totally limited to VLAN configuration only?
View 4 Replies View RelatedWe have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?

I have many Vlans on left side of image , Right Side of Image is having internet connection via Modem, and local connectivity between VLAN works fine but Other Vlans Except Vlan1 is able to Access Internet.Note that 3750X did not have NAT Feature ,How should I able to get Internet on Other Vlans (10,20)
I have been looking to find out the list of features that the IP Base IOS has for the 3750X series switch. What would be ideal is a comparable list but essentially I need to know which of the LAN Base/IP Base/IP Services has SSH functionality.
View 1 Replies View RelatedFull feature set for IP Base with the 3750x.I just wanted to verify that I could create a routed port, turn ip routing on, and create static routes as well as a default route. From what I can find, there shouldn't be a problem with this on the IP Base Feature Set, I just wanted to verify. Or any link for the Features of IP Base on the 3750x.

View 2 Replies View RelatedHad problems with voice quality on VoIP with 4500 series switches and the qos dbl feature (which gets enabled by the auto qos feature)?? I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.
