Cisco Infrastructure :: 2960s / 3750s / 6506 - AC Power Outlet On Catalyst Switch
Apr 15, 2011
I have several 2960s and 3750s and two 6506 (ws-cac-3000w) recently move to new location The power outlet is the same ,but Volt is different current 2960/3750 use this(one phase 3 wire) 220v and new location change to (from 3 phase 4 wire -> one phase 220v)6506 current using(one phase 3 wire) and will be change to (from 3 phase 4 wire -> one phase 220v)
I had search doc about power supply /cable , only show support single phase 220 v ,but not description vlot between each wire !!Does new location power outlet suit for 2960/3750s power and 6500 ws-cac-3000w ?!? Do I need chane power outlet back to current using?

We have one Catalyst 6506 ( with WS-SUP720-3B, IOS is 12.2(18)SXF14 ) and one Catalyst 6509 ( with WS-SUP720-3B, IOS is 12.2(18)SXF17a ). We used WhatsUP to collect I/O & process memory utilization for both switches. The memory utilization for Catalyst 6509 was ok, but it seems not correct for Catalyst 6506 ( show proc memory displayed the total memory is 512MB, but the WhatsUP displayed only 64MB only )

I have a 2960S Catalyst switch in my LAN, with the firewall and the servers in the same VLAN (vlan 3).All the servers and the firewall are in the vlan 3 are in the "192.168.19.0/24" subnet, the firewall has the IP "192.168.19.1".I can land on the firewall with a VPN (192.168.130.0/24) which has a complete view on the subnet 19/24.I can access, manage and get SNMP information of the Catalyst from the servers but I can't do the same from the VPN.Is there some feature I need to enable on the switch in order to allow 192.168.130.0/24 to access it?

I'm using a Catlyst 3550 to supply power to a IP network surveliance camera. By default, the predecesor to POE, Cisco Inline Power allocates 15.4 W of power to a port ... What is the process for reducing this power output?
"For an IEEE device, the switch always allocates 15.4 W to the port. The switch does not display the IEEE class type in the show power inline privileged EXEC command output. Instead, it displays n/a."

I have set up an ACL on my 3750 switch to deny icmp from PC A on our inside network to PC B on a different VLAN on our inside network using the following ACLs:
deny icmp host 10.1.17.15 host 10.3.10.4
deny icmp host 10.3.10.4 host 10.1.17.15
-- or --
deny icmp host 10.1.17.15 host 10.3.10.4 echo-replydeny icmp host 10.3.10.4 host 10.1.17.15 echo-reply
These ACLs belong to an access-list that also limits ip traffic to a few specific machines.When I try pinging from PC A I receive a reply message back from PC B. Shouldn't this configuration block any ICMP from PC A to PC B and from PC B to PC A? I would have expected the first ACL statement to block any packets associated with ICMP and when that didn't work I tried the second configuration.

I've browsed around to the other support strings to make sure I didn't miss anything, but I can't seem to get this to work. I have the latest sl_suspend_ports.tcl and tm_suspend_ports.tcl created by Joseph Clarke from strings that verified they worked as planned. Here are the commands I issued to register the scripts -
Directory of flash:/policies/
9 -rwx 3101 May 3 2013 07:58:03 +00:00 sl_suspend_ports.tcl
10 -rwx 4669 May 3 2013 07:58:44 +00:00 tm_suspend_ports.tcl
conf t
event manager directory user policy flash:/policies
event manager policy sl_suspend_ports.tcl
event manager environment suspend_ports_days 1
[code].....
It doesn't appear to work though. Essentially, we have a need to make sure all computers are always on and all ports not active for >24 hours to be shutdown and moved to a designated vlan (I added the 'lappend' statement to the script to specify the additional command of assigning the vlan) I'm running 12.2(55)SE7 on Catalyst 3560s and 3750sIs there a way to manually run the script? Did I miss anything in the configuration?

I just inherited a network which has 7 switches (3750s) as a Stack. In there, there are 5 SVI (switch virtual interfaces) and in each of these VLANs, HSRP is configured.
Question:Is HSRP really needed in a Stack configuration?If so, what are the benefits?Can I simply clean-up the config and remove HSRP?

i want to know if 1port of the 16 10Gbase-t Module (WS-X6716-10T-3C) for the Catalyst 6500E Series, can be connected to a 1Gbase Port of a 2900 ISR Routers, are they gonig to work at 1Gbps or, simply, they are not compatible?
If it is true, can i create a 4ports etherchannel between them? of course using the 16 1Gbase-T switch module on the Router.

I was unable to configure vlan-based qos on Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(33)SXH6, RELEASE SOFTWARE (fc1) Seems to me my configuration is not working. Here is the output of the interface:
sh int G1/6 | i rate
Queueing strategy: fifo
30 second input rate 25231000 bits/sec, 4282 packets/sec
30 second output rate 46940000 bits/sec, 9257 packets/sec
And here is my configuration:
interface Vlan3
ip address 192.168.1.1 255.255.252.0
service-policy input TEST_IN_PMAP
service-policy output TEST_OUT_PMAP
[code]....
Why I can't see matches in ACLs? I've double checked the direction and seems to me it is correct. I can't see matches even I configure something like this:
10 permit ip host 192.168.1.168 any
20 permit ip any host 192.168.1.168
Why my output rate is higher than 30M? Is it bacause there is no matching traffic here in ACLs? I'm absolutely shure that this host with such ip connected to this interface:
#sh arp | i 192.168.1.168
Internet 192.168.1.168 0 feed.beef.f00d ARPA Vlan3
#sh mac address-table | i feed.beef.f00d

I have two Catalyst 6506 in VSS mode with VS-S720-10G running 12.2(33)SXI1 IP SERVICES.I have two firewalls that communicate on to the other through a dedicated VLAN created on Catalyst 6506.
One firewall is able to ping the other one on this dedicated VLAN but if I send multicast traffic from firewall-1 I didn't receive it on firewall-2.I found a bug related to multicast issues on Cisco WS-C6509-E with VS-S720-10G. The bug ID is CSCtc59038.

We are upgrading a customer network and have found that users of a particular application [which is very bursty/bandwidth hungry] have experienced a marked performance drop. I see lots of output drops on the interfaces. This is only happening on 2960S-48 the rest of the users on 2960PSTL [all PoE] are not having nearly as bad a time.I have tried various QoS configs with little success. I have seen on some other blogs that the 2960S has less buffers than the rest of the family.
Removing QoS or upping the users to 1Gb cures the performance problem.

I have a Cisco 2960S-48FPD that someone was trying to do an upgrade, loaded c2960-lanbasek9-mz.150-2.SE2.bin instead of c2960-universalk9-mz.150-2.SE2.bin. To try and fix it they deleted both but before they could put the proper ios on, another person dropped power. Now the switch will boot into rommon, HOWEVER it won't respond to any keystrokes. It's stuck at "..... flash_init boot " and the switch: prompt. I have tried using both putty and SecureCRT, the settings are correct, the usb-serial works on another c2960S. I can read the output when it goes into rommon so it's not a baud rate issue.

I have a pair of switches stacked:
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 52 WS-C2960S-48FPS-L 15.0(1)SE C2960S-UNIVERSALK9-M
* 2 52 WS-C2960S-48FPS-L 15.0(1)SE C2960S-UNIVERSALK9-M
When I try to enable ip sla responder on the stack I get:
%SYS-3-HARIKARI: Process IP SLAs Responder top-level routine exited
I have been able to find a bug in the toolkit. Should ip sla responder be supported on the stack as above?

Just I have upgraded some 2960S to IOS 15.0(2)SE from a IOS 15.0(1)SE3 and the catalyst don't switch any IPv6 traffic. Don't work any RA and also don't work any unicast IPv6 traffic from any interface. I can see some references to IPv6 changes in the FHS (First Hop Security) in the Release Notes, but no any reference to changes in the configuration.
The switches don't have any IPv6 specific configuration and the sdm is the default templata. Returning to 15.0(1)SE3 everything work ok.
On Catalyst 2960, and 3560E this IOS version seem to work fine with IPv6.

we have Catalysts 2960S for switching in our Wireless high capacity backbone network. As agregation switch we are using 3560x.
I just need to know, if are these 2960S good solution for igmp snooping for whole IPTV stream. It put only a range from backbone and put out on another port. But just specified multicast addresses.
Imput will be 239.128.0.10 to 239.128.0.20 on Gi 0/1,Output wil be 239.128.0.10 - 15 on Gi 0/24
IPTV will be separated on different VLAN for eg VLAN 20,Is needed any priorization configured od switches?,The capacity for IPTV is around 500 mbps

I recently tried to manually format the flash on a model WS-2960S-48TS-L switch running IOS version 15.0(2)SE. While executing the operation I got the following error - mifs[8]: Failed to create superblock %Error formatting flash (I/O error).As a result the flash is no longer accessible by the switch. I spoke with Cisco and they indicated that a switch reload would remount the flash and make it accessable again but the .bin file would need to be reloaded using the xModem recovery procedure (what a pain).The next IOS version 15.0(2)SE1 will supposedly fix this bug but it has not been released yet. In the meantime if you are running 15.0(2)SE you may want to hold off performing a "format flash:" function on a 2960S.

We are using catalyst 2960S Lan Base IOS on Radio towers. We just bought 50 Accest points, thas are GPS synchronized. Problem is the APs need to be connected on L2-mac betwen each other. But at this time we are using port isolation on each switch (tower) by protected port function to isolate clients from each other.
My question is, is possible to specifi a Mac addresses in specific vlan thats can comunicate betwen protected ports? On tower is one Master unit and others are slave. I thing there is only 1 dirrection comunication - from master to slave.

I have a 2960S connected to an RSP 2300. The 2960S is currently running off of the RPS, and I would like to switch it back to the internal power supply. Can I just run "power supply 1 on"? Will this cause the switch to reboot? Also I am concerned because when I do a show env power it shows: [code]
Is it normal for the internal power supply to show Unavail when running off RPS?

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?
