Good follow up question Georg.. Back in the day, waaay back, I was around when this unit was installed, so I know a separate power supply unit was not purchased or installed with it, but didn't recall if the unit by default had a second internal power supply. My own research came up with conflicting results hence post of the question if there was a way for me to tell, without me having to physically go to the datacenter. When Reza pointed out in the datasheet there is no default internal option for a second power supply I knew we only have the one. But again that's a good question for future reference for anyone that may have the separate unit, if it would show up or not in the command line. Thanks again everyone for all the help!!

Thanks for the info Georg! The command response with "Power is OK" Looks like a trip to the Datacenter....

I have a WS-C3560G-48TS, (S/N FOC1117Z64V) and need to check whether or not the switch has redundant power supplies or not. Is there a way to do that remotely or do I need to make a trip to the datacenter? I did find the "show env" command and received the below results, but it doesn't necessary answer my question.
show env all FAN is OK TEMPERATURE is OK Temperature Value: 42 Degree Celsius Temperature State: GREEN Yellow Threshold : 56 Degree Celsius Red Threshold : 66 Degree Celsius POWER is OK RPS is NOT PRESENT
Thanks!

Yes, and I've confirmed it by doing a "show vlan" command. I do see that Vlan 15 exist and that port is assoicated to that vlan. Thanks

cadet.. Is there something specfic you'd like to see? I'd be happy to post specfic areas if you can let me know what you might be looking for. The reason I ask is the config is full of senstive information that I'd prefer not to share. Though I can go through and edit it to hide most of that information, it's very time consuming. Again something I can do if necessary. Thanks, Bob

Hello all, I've recently connected a previously unused interface from our F5 LTM to our 3560G switch. I have the LTM interface and switchport interface both in the same VLAN. However when I do a "show mac-address-table int g0/48" the interface doesn't have a MAC address showing. The "show int g0/48" shows the below results. (no errors shown below that either). Basically the overall problem is we have a server connected to the switch with an IP within that Vlan, the server's switchport is also in that Vlan, but I can not ping the server from within a shell command from the LTM, but I ping it from the switch itself. When I run a TCPDump from the LTM I see the following: [LB1:Active] config # tcpdump -ni VLAN15 -s0 host x.x.78.44 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on VLAN15, link-type EN10MB (Ethernet), capture size 65535 bytes 14:22:50.358148 arp who-has x.x.78.44 tell x.x.78.31 out slot1/tmm0 lis= 14:22:52.358375 arp who-has x.x.78.44 tell x.x.78.31 out slot1/tmm0 lis= SW1#show int g0/48 GigabitEthernet0/48 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 001b.90e3.d0b0 (bia 001b.90e3.d0b0) Description: LTM1-p1.6 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 1000Mb/s, media type is 10/100/1000BaseTX SW1#show run int g0/48 Building configuration...

Again they are on the same VLAN, I can ping the server from the Switch and the firewall with no issues. All the other LTM interfaces are working fine and I see MAC addresses showing up for those interfaces in their corresponding swtich ports. Thanks, Bob

I've got two two 3560s switchs, (WS-C3560G-48TS-S) that I'm trying to connect to each other using the GB ports over Fibre. We purchased the following GBICs, SFP 1000SX Transceiver and when we put them in the port it shows (err-disabled). Below is some information I pulled from one of the ports, but doesn't matter what port I use they all say the same thing. Any suggestions on what I might be dowing wrong here or what else I can look at to fix it. ProdSwitchSW1#show run int g0/51 Building configuration...

Leolaohoo, is correct. On a Loop test it's possible to have the interface read Down/Up. I reached out to the interviewer to get more information on that question. He said a Loop test, can cause the interface to show that, it will actually show some other weird results too, but that's how it's possible. Thanks everyone for their feeback, I appriciate the help!

That's kind of what I thought too, they meant UP/Down, however the question read Down/Up I thought it was odd too, only thing I could think of is that they left administratively part off the Down section to throw me off, but I find it hard to believe that it wouldn't ever be possible to see that, kind of like a trick question I think.. Thanks, Bob

I was recently asked this question in an interview, and since I haven't worked with routers in some time I couldn't really answer completely so for future references I was hoping some one could help me with a correct answer. This is all the question had to it, I'm sure I could have followed asking for more details, but I think they were looking for more general answer, and I didn't want to look even worse by getting more confused with more details. Any help would be greatly appreciated. On a Cisco router, is it possible to have an interface show DOWN/UP? If so, when? Thanks, Bob

Reza..Yes that's excatly what I'm trying to do.. I have added the new vlan IDs to the VM side, however my vm server is not able to get out to the network, but I can see in the switch that the MAC address is in it's table so I was thinking this may be the problem, because I'm using 1 Interface on my firewall to "host" two subnets/vlans but the switchports they are connected to only allow one VLAN. So I thought maybe the problem was that because the switchport was only set to allow VLan 8 traffic to and from that firewall interface that was my issue. When we attempted this the first time the servers connected to the switch that were using that VLAN 8 would stop communicating when we attempted to lock the trunk down to only new vlan and the orginial.. At the moment I still can't get my VM server to see the outside world..

Yes the firewall does see the other VLANs, each interface on the firewall is assigned an different IP from all the subnets we run and those interfaces are connected to switch ports that are assigned to a specific VLAN that we've deemed to be assoicated to that subnet. We do not have any issues with our Web Servers talking to our App Servers which both are in a two completely different subnet/vlans. Bob

John, I thought about that too, and makes me think we've not correctly using Vlans. Our switches have something like 10 Vlans, however the switch only has one IP address. For example, the switch itself has an IP of 192.168.69.5 and that's the only IP it has, but the server connected to the switch has an IP of 192.168.70.10 and the port its plugged into has the Vlan 8 associated to it. The 192.168.70.x IP range is only associated on the firewall's interface and nowhere else in the environment. The firewall is a CheckPoint firewall, not by my choice, I inherited this thing.. :-) To me were may not using Vlan correctly since there is no IP assoicated to it.. Right? Thanks, Bob
