Since upgrading a 3750x switch stack to version 15, PC's on the network do not get a DHCP lease. The only way to get them to work is disable and re-enable the NIC card.
Downgrading the IOS does not downgrade the microcode on the switches.Is there anyway to downgrade the microcode?
I have a WS-C3750X-12S-S (IP Services) that I THINK I'd like to downgrade to LAN Base so I can stack it with a WS-C3750X-48T-L that is already LAN Base..
View 4 Replies View RelatedAfter trying to downgrade a Nexus 7K from 5.2.1 to 5.1.5 by updating the boot & kickstart boot statements and reloading, I'm now stuck in an endless cycle of reloading. See below:
Is there a break sequence which will allow me to modify the boot statement back to the original via ROMMON or something similar?

We made an IOS doBlades on switch 4507R keep block after an IOS downgradewngrade. Before to do it, the equipment comes with blades 1, 2, 3, 4 and we insert "X4418" and "X4548" on blades 5 and 6.[code]
After we made an IOS downgrade to a cisco 4507R from "cat4500e-ipbasek9-mz.122-54.SG.bin" to "cat4500e-entservicesk9-mz.122-53.SG2.bin" (comes with a redundancy supervisor blade WS-X45-SUP6L-E) the standby supervisor keep disable.We tried with the command "Switch(config)#boot system flash cat4500e-entservicesk9-mz.122-53.SG2.bin" then save configuration and "reload" comand but the switch runs with the "...54.SG.bin" IOS.
We erase the configuration with the command "erase/all non-default", before to apply the reload command insert the "entservicesk9-mz. 122- 53. SG2.bin" using the tftp command.The standby supervisory remains on disable state but the active supervisory runs with the desire IOS. In order to downgrade the IOS to the standby supervisory the active supervisore was removed temporarely (previously the switch was off) to make the standby as active, after that made the same procedure with command "erase/all non-default", "copy tftp://(....122-53.SG2.bin), and "reload" command.
The switch was off and re-insert the active supervisory and turn on the switch, after we made the procedure the blade "WS-X4548-RJ45" marks a fault as follows: [code]
The blades were reset but don't have access to them.
Is there a way I can downgrade the firmware on a C3750 v2 switch 24TS-S v07 to 12.2(35) SE5. I have added this new switch to an existing stack but the FW is not compatable. I believe the answer is to upgrade the rest but I cannot afford any down time as they are used to run a CCTV securiy network 24/7. I have included details below to assist with my problem. Switch 4 is the one with a version miss match.

specifying Cisco devices and I've made an error.I have 2 Catalyst 2960S switches (C2960S-24PS-L).Based on this snippet of web copy from the Cisco website:What's new for the Cisco Catalyst 2960-S Series Switches with LAN Base Software: # 10 and 1 Gigabit Ethernet uplink flexibility with Small Form-Factor Pluggable Plus (SFP+), providing business continuity and fast transition to 10 Gigabit Ethernet I bought a cable assembly "SFP-H10GB-CU3M" (3 meter copper twinax cable with 10GB SFPs on each end). Unfortunately, it appears after more careful reasearch that my specific model 2960S's are not directly compatible. , can I force these 10GB SFPs down to 1GB and get them to work with my switches or do I need to return and repurchase?

View 2 Replies View RelatedI have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.
I have an 1811 with several subnets connected to it.I recently installed a 3750x plant and want to bring my interior routing back to it.
All the routing is handled by the 1811 via secondary interfaces on vlan1?
I have 192 ports, and subnets show up on almost all of them. None of the ports are assigned to any specific vlans. Most ports have several subnets on them.
What is the best approach to getting the 3750x to handle the routing?
my company pay a switch 3750 X. WS-C3750X-24T-E. It uses IP services basically but I failed to configure InterVLAN routing. why interVLAN routing doesn't work on my switch?
View 10 Replies View RelatedI am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.

How to know whether QoS work on the 3750X or not ? Is it correct about the config in scenario A ?
I have a one question. I am using Cat3750x-48 switch. Suddenly it has occurred following high CPU log message in Cat3750x-48 switch.
%SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 62%/0%, Top 3 processes(Pid/Util): 162/40%, 156/10%, 74/1%
What is meaning of PID 162 ?
There seems to be a lot of conflicting information on what can and can't stack together in the 3750X range.
I know that LAN Base can only stack with other LAN Base switches.
Can IP Base stack with IP services in 3750X? I have also heard that the 15.x.x IOS restricts mixed feature set stacks?
I know that Cisco recommends that all switches in a stack have the same IOS and feature set but having all IP Services in a stack can get too expensive.
I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.

I am building a switch stack using 4 48 port 3750X switches that will also have the power stacked. If I install a single 715W power supply in each switch will the stack support 802.3af accross all 48 ports on each switch? My calculations are 48 ports x 15.4W which gives me almost 740W needed which is over hte 715W power supply. I was reading somewhere were it mentioned that in a powerstack additional power can be drawn from the stack. I know this will not work if you are trying to support power on all switches accross all ports but would it if say 2 of the 4 switches are needing to provide PoE accross all 48 ports? If I say we can only use 24 ports per switch for PoE that drops the power need down to 370W which I believe should work. Just trying to get a better understanding of PoE consumption. Would the best solution be to just add a second power supply to each switch?

View 12 Replies View Relatedwe are replacing network equipment at one of our sites. The network will have 12, 3750X switches(6 stacks) - one stack will be the core. A 1002 will be the WAN router to the Main campus. The 1002 will connect to the core via 2 ethernet cables. I'm debating whether to use L3 or L2 between the router and Core. I've heard that routing is more efficient if L3 is used and also I will be able to create an L3 etherchannel between the 1002 and Core switch. See the attached doc.

View 1 Replies View RelatedI recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.
