Recently on two switches, both being same cisco WS-C3750E-24PD, running with same IOS c3750e-universalk9-mz.122-58.SE2.bin got noticed that the license state of one switch is showing incorrectly as shown below [code] I will not be able to execute any changes/modifications on switch as of now.
View 9 RepliesI have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

I have configured a SVI in my 4500 ( Sup 7-E 10GE,,,,,,and,,,,,cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin) switch and it is showing Down Down, because there were no active switch port in the vlan, I added one switch port to this vlan but this port also in the down state, so i added the SWITCH PORT AUTO STATE EXCLUDE command under this port, even after this also the SVI never came up, So i added one systen to the port so both the switch port and the SVI came up...So why SWITCH PORT AUTO STATE EXCLUDE command have no effect in this model of the switch..

I have a pair of 3750E-24PD-S stacked together, it seems after stacked together the stacked switch always flood the console screen with these messages which are not true: [code] Switch-2 is the stack member, Switch-1 is the stack master. The RPS fan failed refers to RPS2300 or the internal power supply of 3750E? Even when I turned on the RPS2300 the stacked switch still display the messages. Also I have two RPS2300 serving stack master and stack member respectively both RPS2300 were switched off why the messages only refer to Switch-2 and not Switch-1? [code]

My question is about WS-C3750E-48TD-S and WS-C3750E-24TD-S Switches
What are the limitations of the mapping of VLANs on this device? Is it limited by number or by interface? Does the configuration of an interface has spread all interfaces ?
I have a C3750E-24TD-S on which I just loaded new firmware. When I boot up I see this:Loading "c3750e-universalk9-mz.150-1.SE2.bin"...c3750e-universalk9-mz.150-1.SE2.bin: no such device

I have two Switches which i need to put in a same stack - WS-C3750E-48TD and WS-C3750G-48TS . Possible to do so and also which IOS to put in both the switches as WS-C3750G-48TS is having lower RAM and flash.Whether can i put following IOS in these switches and connect them in a stack as i have read that IOS -- 15.0.1. SE are compatible with both the switches.
a . c3750e-ipbasek9-mz.150-1.SE.bin in switch - WS-C3750E-48TD
b. c3750-ipbasek9-mz.150-1.SE.bin in switch -- WS-C3750G-48TS
Is that possible add WS-C3750-48TS-E to ws-c3750e-48td stack?

As above, I got a problem with C3750e, ios c3750e-universalk9-mz.122-58.SE1.bin, when send AF41 traffic passing through it. My topolygy is as following
WAN link <----------> G0/0/2.100 - ASR1002 - G0/0/5 <---------> G1/0/1 - C3750e - G1/0/3 <--------> G0/0/1 - ASR1004
On this C3750e, I turned on mls qos, trust dscp on both G1/0/1 and G1/0/3 and no else is configured. ASR1002 G0/0/2.100, i applied the CB shaping fror AF41 traffic.
C3750e#sh mls qos
QoS is enabled
QoS ip packet dscp rewrite is enabled
C3750e#sh mls qos int g1/0/3
GigabitEthernet1/0/3
trust state: trust dscp
[code]....
Then, from ASR1004, i send ICMP traffic with TOS set to AF41 (136) and i found out that
1. The traffic is dropped on c3750e
sh mls qos int g1/0/3 statistics
GigabitEthernet1/0/3 (All statistics are in packets)
30 - 34 : 63 63 48 86 1534
2. The traffic never get hit into AF41 class in ASR1002 ? Why C3750e dropped this AF41 traffic? and what can I do to fix it?
I'm trying to boot this IOS on a 6506-E, s72033-adventerprisek9_wan-mz.122-33.SXI8.bin.
This is what I see in bootvar.
sh bootvar
BOOT variable = disk0:s72033-adventerprisek9_wan-mz.122-33.SXI8.bin,1;disk0:s72033-ipservicesk9-mz.122-18.SXF8.bin,1;
CONFIG_FILE variable =
BOOTLDR variable =
Configuration register is 0x2102
Standby not ready to show bootvar, I want to remove SXF8 and leave SXI8 alone. I removed both IOS file names in boot system and added the SXI8 again and saved. So this would be the output after.
But after a switch restart, this would be the output of show bootvar again.
sh bootvar
BOOT variable = disk0:s72033-adventerprisek9_wan-mz.122-33.SXI8.bin,1;disk0:s72033-ipservicesk9-mz.122-18.SXF8.bin,1;
CONFIG_FILE variable =

Is there anything I need to check? This is an old engine and I'm not sure if the variables of the RP modified .
I am looking for an IP Services IOS image for a WS-C3750E-24TD-E switch.Currently have a two switch stack composed of WS-C3750E-24TD-E & WS-C3750G-12S-E.Current IOS running: IP Base.
I need to be able to remove the stub mode for EIGRP, so I am looking for an IP Services image for WS-C3750E-24TD-E switch to be able to run full EIGRP. But I am not able to find one. What is the main difference between WS-C3750G & WS-C3750E switch?Is this even possible for the WS-C3750E?
I'm thinking of connecting a branch office to the main office with just using multilayer switch. The sites will be connected using ethernet leased line, so I'm thinking of connecting it directly to the switch.
We're running eigrp on our network so the Multilayer switch will do the eigrp routing.Thinking of using C3750E-24TD-E (IP Services) as the multilayer switch. Can this work or do I still need a router to terminate the WAN?
I would like to request assistance from all the gurus here for an issue i have with a Cisco 7513MX PSU. There probably arent many people who are aware of 7500 chassis as they are quite old.Isse: PSU 1 failed in chassis and we tried to replace it. Once replaced, we are getting the following output for it:
1#sh env all
Arbiter type 2, backplane type 7513MX (id 2)
Power supply #1 is TBD (id 0), Power supply #2 is 1200W AC (id 1)
We have been researching on the internet for answers but unfortunately due to the age of this model, there is very limited information available. We did find information which suggested to have BOTH PSU 1 & 2 with same revision. Right now the chassis is running only on PS2, we dont want to take down the chassis just to confirm the revision number on the PSU and there is no way to see that on the CLI. What we can do is get another pair of same revision PSUs, insert PSU1 first THEN take out PSU2 and then insert the same revision as PS1 in PSU2 slot but the moment we insert PSU1 in we get that TBD state which is not normal status and raises our doubts about putting the same revision PSUs with the method above, there is a chance that after we insert PSU1 in, the moment we take out PSU2, the chassis might not run on PSU1 due to its abnormal state.
I am trying to setup VLANs and most of configurations are working ok now except IP address assignment from DHCP. If any computer in VLAN 120 or 130 configured with manual IP address, then all works fine. It can reach internal servers and the internet without problem.If the IP address is assigned automatically then any computer in VLAN 120 or 130 are obtaining IP address (strangely!) from VLAN 100. Because switch ports that connected to the computer belongs to VLAN 120 or 130, the computer cannot reach internal servers and the internet with ip address from VLAN 100 . All SVI interfaces for VLAN 100, 120 and 130 have ip helper-address option defined pointing to the DHCP server. No DHCP snooping enabled on all switches at this point. DHCP server have three scopes for the three different VLANs.

I have two Cisco 6500 switches connected via fiber, this is my small network. One end goes to a provider, and the other end goes to a server. My IT department wants some sort of link state propagation since the provider keeps going down, but the IT team is unaware until they contact me.
We provide a Layer2 point-to-point circuit, access ports at the ends. We use V LAN's to transport the traffic. Please let me know if there is anything I could do to support link state propagation.

I am testing 2960 24 S with storm-control and Errdisable Port timer interval 60s , connected HUB on fa0/17 to make traffic / loop.After Strom Control detection the interface goes down thats ok after 60s they will try to recover the interface and going up although the loop is still there.For my understanding if the interface detect still a loop on that interface they will disable the port again for 60s and will check again.

We inserted a new module with 48 rj45 ports in a 4500 with just one supervisor module. We have two 4500, and we tried the new model in the other 4500 and it´s working properly and giving a OK status. Furthermore, the module´s LED status is green. We saw that there are 8 ports (from 17 to 24) that are in faulty state, so probably this is the cause for the faulty state for the module.
We tried already a Hw reset, replace/insert again the module...
We are almost sure that it can be a Hw failure. We are getting the following results different commands:

We have a pair of 6500 switches, each having a trunk going to each access switch. We set the spanning tree priority on Core1 so it is the root bridge for all VLANs. We have two different types of access switches:
-3550 setup as VTP client and ISL
-2960 setup as VTP transparent and dot1q.
Pruning is disabled but we use "switchport trunk allowed vlan" to restrict which VLANs go through each trunk. When we need to permit a VLAN through a trunk, we simply run "switchport trunk allowed vlan add <VLANID>" on the access switch and both core switches. If it is a 2960 in VTP transparent mode, we must set the VLAN to active. Once this is done, a "show int trunk" will reflect the new VLAN in "Vlans in spanning tree forwarding state and not pruned" for Core1.
I recently went through this process to add VLAN 250 on a 3550 access switch, but the VLAN is not listed in STP forwarding state and not pruned. I tried removing the VLAN from the trunks and redoing it, but there is was no change. I tried adding VLAN 257, but the same behavior happened. I then tried trunking the same VLANs to a few other access switches. Three other 3550s experienced the same behavior, but I was able to trunk the VLAN to a few 2960 switches. At this point, I figured it might be related to some kind of limitation of VTP or the 3550 switches. I provisioned a new 3550 with the same IOS and settings (VTP client, ISL). To my surprise, all VLANs configured were in STP forwarding state and not pruned.
Running show spanning-tree on the core and access switch shows VLAN 250 as designated FWD. I confirmed we are not hitting the limits in "show spanning tree summary totals" on the Core or Access switches. I also confirmed we are not hitting the virtual port limit by running "show vlan virtual-port slot x."My next action might be to shut/no shut the uplink to Core1 from the access switch, but I'm not sure if that will fix it and even if it does, I have no clue what caused the issue.
I have a Catalyst 2950G when I activate the switchport port-security, but I want to empty the black list of mac address because every time I connect a device, the port is automatically désacative, here is the port configuration:
!
interface FastEthernet0 / 2
switchport access vlan 17
switchport mode access
switchport voice vlan 51
[code]....
I tried the following commands to clear the blacklist mac address of that port, but the problem is still relevant:
# Clear mac-address-table dynamic int fa0 / 2
# clear port-security all int fastethernet 0/2
# clear errdisable interface fa0 / 2 vlan
I have catalyst 6500s with two VS-S720-10Gs, one is in Active and one is in Hot state. Both Sup cards have two 10G uplink ports. How does the traffic forwarding works in this case on the uplink ports? Do these uplink ports actively forward traffic or it is only the uplinks ports on Active that forward traffic? I see CDP neighbors on both Active and Hot SUPs uplinks ports - it indicates that packets are flowing on both cards.
I want all uplink ports on both SUPs to actively forward traffic. Does it work? What is the config for this?
