Cisco Switching/Routing :: Catalyst 4500 - Maximum Power Cable Length?
Feb 11, 2013
I am relocating UPS units and will need to buy longer power cables to extend from our 4506 and 4510 to the new location.I think I am looking at 15 to 20 feet but I am going to confirm. Is it okay to use longer cables?
If I'm upgrading dual redundant power supplies in a Catalyst 4507 from 1000W (data) to 1400W (data), can it be done without taking the switch through a power cycle? I'm guessing no as I read that the switch will not recognize a 1400W PSU in bay 2 if there is still an original 1000W PSU in bay 1.
I just recieved a new 3560-x switch with the C3KX-PWR-715WAC. It looks like Cisco is now using a different AC power cable. Not the StackPower connector, but the standard AC power cable. My data center is setup to supply 208v using C13 power cables. The switch uses a C15 power cable, and comes with a standard NEMA 5 to C13 power cable. Does Cisco make, or officially support a C13 to C15 power cable? Can I still use a 208v power supply with these switches? I'm using an APC AP8861 power distribution unit, see [URL]
I used 2 PC with gigabit NIC, use cat6 with short cable i've got speed 1000Mbps, but with longer cable(around 30meters) speed is 100Mbps. I'm looking forward to seeing from you soon.
I am running a wrt54g and I was woundering what is the longest rj45 cable length I can run?
I notice running about 30 plus feet connection does not work. When I cut off about 5 feet it worked. Seems I can only run a ceratin amount of cable length with this router.
I have a Linksys BEFSX41 wired router. If I wanted to connect a second computer to my router, what would be the maximum length of cable I can use without experiencing any problems ?
how far apart an Aironet 1410 Bridge can be from the Power Injector (Dual Coax feeds). I just can't find the specification details. The device comes with a 20' and 50' F-type and I'm looking at 150' runs for both ends of the bridge pair.
I am trying to setup the WOL for our enterprise. We have a C4500 setup with mutliple Vlans. We are using Microsoft SCCM server to wake up workstations for security update. The workstations are on vlan190 and the Microsoft server is on vlan 441
Here's my config
the config below
interface Vlan190ip directed-broadcast 100 (Enables the translation of a directed broadcast to physical broadcasts) access-list 100 remark ====== Wake-On-LAN ======no access-list 100 permit udp host 10.4.40.98 any eq 9 logaccess-list 100 remark ====== End of ACL 100 ======
I am trying to understand the implicit limit to the priority queue. I know you can define an explicit policer but if you don't I can't find out what the rate limit really is.
I've two Cisco 4500 running as core switches for huge and complex network. The two 4500 are going to act as dhcp server for several subnets. The easiest solution would be to split each DHCP pool in two, and assign the first half of the pool to one of the core switch and the second half of the pool to the second core switch. This would be a partial solution since if one of the two fails, the second core switch would not have enough dhcp leases available for all the devices connected for each subnet.For such a reason, I'm wondering if it the 4500 switches support a stateful redundant DHCP servers, so that the two switches can synchronize their DHCP lease tables. If this feature is available, I could define the same pools for both the switches without the risk of having duplicate ip addresses within the network.
We have a Switch Catalyst 4500, model WS-C4510R+E, with 2 Supervisors, models V-10GE, which is showing high CPU values all times.When this occures, the switch shows 95-100% for total cpu for a few hours at a time.show proccesses cpu shows process Cat4k Mgmt LoPri with an unusual cpu value of 56% The show platform heath command gave me a high reading for K2L2 Address Table R which is curently 9,45% but the last hour is around a 20% average CPU ?[URL] what the process K2L2 Address Table R means and what could be the cause of this peak?
I have a Catalyst 4500 WS-C4506 and S-X4516-10GE Supervisor running under IOS 12.2(52)SG IP BASE SSH. After having installed IOS 12,2(53)SG i wanted to schedule a reload. After entering the reload at command I get the message %Reload in Progress and nothing happens.
is it possible to run a Catalyst 4500 as pure Layer 2 Switch, i.e. disabling "ip routing", but still managing the switch via Fa1, i.e. the defautl mgmtVrf vrf ?I tried the following:
! no ip routing ! interface FastEthernet1 ip vrf forwarding mgmtVrf ip address 192.168.1.1 255.255.255.0 ! ip route vrf mgmtVrf 0.0.0.0 0.0.0.0 192.168.1.254 ip default-gateway 192.168.1.254
I was not able to reach the Switch even from the same subnet. Only after enabling ip routing I could manage the Switch. I haven't found any command to set ip default-gateway for a vrf. Any workaround to keep routing disabled, but still manageable via VRF?
I was reading the documentation of the Catalyst 4500-X for creating VSS and MEC (multichassis etherchannel).In the VSS specific part, it's written"Cisco Release IOS XE 3.4.0SG does not support Layer 3 MEC".
Can I still use VlanX interfaces ad route through them?In my setup I only have IP addresses assigned to vlanX interfaces (with some VRF-lite magic)[code] Does that sentence only mean that I can't have IP assigned directly to the MEC?
can I plug power supply from 4500 to 6500? more specifically we have power supply PWR-C45-1300ACV. And we need to place some power supply to 6500, which has only one active module. So 1300 should be enough for it. But we dont know if they are physically compatible, if it is possible to plug. I didnt find this power supply to be officially?
I am trying find out what the nominal power draw is for the following switch. The installation manual and data sheets says that the power draw for the units are 15.1W and 15.7W maximum at 18VDC. I am trying to use the switch for a solar application (12VDC) and would like to find out what the nominal draw would be when the device is in standby or if all of the ethernet ports are unused. I plan to use the two fiber SFP's and one copper port.
How can I find out the firmware versions for IOS, modules and components of Cisco catalyst 4500 series switch. I can see the firmware version of IOS in show version command but how can I find it out for the modules or components of the switch.
On 45XX catalyst , bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group. Example for the following line card : WS-X4448-GB-SFP
I want to know if there is the same mecanism on 3750X switches. I mean is bandwidth allocated across a group of ports like on 4500 catalyst ?
I have 2 x WS-X4548-GB-RJ45 Catalyst 4500 Enhanced 48-Port 10/100/1000 Base-T (RJ-45) line cards in a 4500 chassis with 2 x WS-C4507R-E E-Series Super visor engines. We would like to create a layer 3 ether channel from a access layer switch terminating on our 4500 chassis. Can we configure the ether channel from the access layer switch such that one port on the ether channel is on one line card and the other one is on the other line card?
I just received a new 4510R+E switch with CAT4500e SUP7e Universal Image cat4500e-universal.spa03.01.01.sg.150-1.x01.bin software imag with License Level ipbase. We specified in the order to receive CAT4500e Universal Crypto Image with License Level ipbase. I have since requested and received the latest CAT4500e Univeral Crypto Image cat4500e-universalk9-spa.03.04.00.sg.151-2.sg.bin. Is there anything other that just installing the new image that must be done to allow me to use the Crypto Image? Would this upgrade do anything to change my License Level ipbase?
Does a new Cisco Catalyst 4500 series supervisor 7L-E model WS-X45-SUP7L-E is backward compatible with a Cisco Catalyst 4500 series chassis model 4507R? I've checked on Cisco website for that Supervisor and it shows only new chassis models WS-C4507R+E and R-E, but what about old type of chassis? We need to upgrade that Supervisor as it's out of line, but we don't really want to buy a new chassis as well as it's going to be very pricy.
We want to filter IP traffic by MAC address on Catalyst 4500. Since we are using bonding (active-backup mode) we need those mac addresses appear on different ports. Below are solutions that we have tried: ACL but it does not work since mac acls only match non ip traffic (We CAN NOT use ip acl). Use a static mac address-table entry to ALLOW specific mac addresses. It does not work either since the same MAC address needs to be seen on a different port. Catalyst 4500 does not support auto-learn option (as e.g. Nexus 5000).
I found a bug in Embedded Event Manager, on Catalyst 4500-E platform with supervisor V-10GE, on various IOS releases (in particular 12.2-50-SG IP BASE w/o crypto, 12.2-54-SG1 IP BASE w/o crypto, but also other releases included latest 15.0-2-SG1 ENTERPRISE SERVICES SSH).The problem is that when you set up a EEM applet that monitors syslog pattern matching, and you also configure remote host logging *with* the option "sequence-num-session", when the match occurs, the switch reboots with message:
Sw (sometimes prints a number instead) VECTOR D00
and in some cases performs a second reboot with message:
VECTOR 0 DOUBLE FAULT
The reload reason message is:
System returned to ROM by abort at PC 0x0
The problem does *not* occur if remote logging has not the option "sequence-num-session". I verified this behavior on various configurations (included our production 130K long *and* factory defaults after erase startup-config).The configuration statements that cause reload are, for expample:
