May 1, 2012I can't seem to find any info on how to configure 2 DHCP server pools on a C3750, to use with 2 user vlans. The purpose is that users in vlan 1 should get an IP address from DHCP server1, and users in vlan 2 should get an IP address from DHCP server2. Both DHCP servers are configured in a stack of C3750 switches, which acts a a L2 switch.

Sep 5, 2012Is this supported on a 3750X ?? A router has two VRFs and its lan interface is a trunk with 2 VLAN IDs, let say VLAN 10 and VLAN 20. The ip address subnet of these two vlans is the same (therefore , they are in different VRFs)
fa0/1
VLAN 10 = 10.15.4.9 (VRF A)
VLAN 20 = 10.15.4.10 (VRF B)
This router is connected on a 3750X switch. There is a firewall connected to this switch also, which is default gateway for several VLANs including VLAN 10 (10.15.4.1)
The goal is that VRF B ip can talk to 10.15.4.1 and VRF A can talk to 10.15.4.1 but VRF B can't talk to VRF A (10.15.4.9 <-> 10.15.4.10)
FW |--- TRUNK VLANs 1,2,3,4,10 ---------| SWITCH |----- TRUNK VLAN 10,20 -----| ROUTER (vlan 10 = VRF A, vlan 20 = VRF B)
I think this is not supported on the C3750, as my promiscuous port is located on a trunk.
Cisco Switching/Routing :: Nexus 1000v Don't Use Private VLANs
Aug 28, 2012We have a requirement for private VLANS for DMZ hosting within one of our datacentres. I just want to query how private VLANs would work in our environment.We have physical servers connected to fex ports (2 fex per rack for each 5k) of a 5548UP switch, virtual servers using the nexus 1000v (vmware hosts connected to fex ports) Out firewalls and load balancers are connected to an upstream pair of nexus 7ks using vPCs.My question is this, ordinarily the firewall would be in a promiscuous port but as these reside on a physically separate switch will the normal vPC trunk still be sufficient or would the "switchport mode private-vlan trunk promiscuous" be required on the vPC up to the northbound 7k.As these connections are already in production I do not want to affect the existing traffic that doesn’t use private VLANs.

Nov 12, 2012I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature?

Nov 29, 2011We currently have a HP blade platform which has two Cisco CBS30X0 switches built into it running Version 12.2(55)SE. These are connected to two Cisco C2960 aggregation switches running Version 12.2(44)SE6. According to this article I need to upgrade these to 12.2(25)FX: url...
1.)This will according to that article only allow me to create edge ports on them, is this a hardware limitation or am I just not finding what firmware I need to upgrade them to, in order to allow the creation of community VLANs? We have these aggregation switches conncted directly to multiple types of firewalls which take care of each of our clients networks including internet access etc. We are wasting many VLANs and IP addresses with our current setup so I am hoping to move over to using private VLANs. The setup of the private VLANs looks simple enough.
2.)When the private VLAN's try to communicate, all info will be sent directly to the layer 3 device I gather, which will not need to know anything about the private VLANs?

Cisco Switching/Routing :: WS-C2960S-48TS-L / Reasons To Limit 1Gb Capable Switches To 100Mb?
Jul 8, 2012Our network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.
Cisco Switching/Routing :: C3750 - Data Center / IP Routing
Feb 21, 2013I have a problem to solve in our data center, see attached drawing. HW: Our core switches consists of two stacked C3750 with ip routing. What I want to do is probably simple but I haven't been able to figure out the best method.
VLAN10 and VLAN20 should not be able to communicate with each other. (ACLs?)VLAN10 will have it's own default route/firewall. Both VLAN10 and VLAN20 should be able to send server backups to server in VLAN30. All 3 V LANs come in on a trunk from a pair of stacked C2960-S. I need it to be able to scale if we have 50 VLANs for instance, hopefully without long complicated ACLs. I've been considering VRF's, PBR but can't decide what's the simplest solution to this problem. I have never done this before so I would prefer to start off on the right foot.

Cisco Switching/Routing :: C3750 SFP Failure After Reload
Mar 11, 2013I have a cable from an SFP module in a WS-C3750-48P with 12.2(55)SE1 running to a Gigabit port on a Cisco WLC. After the switch recovers from a power failure, the gigabit autonegotiation fails. The cure is a long drive to unplug and reseat the SFP. Note this happens at too many similar sites for this to be a loose connection. Interface shutdown then 'no shutdown' is not sufficient. The state is 'line protocol is down (not connected)'. Interface is configured for switchport mode trunk (auto speed, auto duplex). Command 'switchport nonegotiate' makes no difference. Is there a more powerful command than 'shutdown' which might toggle the interface signals? Is there some way of resetting the SFP? sh int gi 1/0/1 displays 'media type is 10/100/1000BaseTX SFP' and zero packets received.

Cisco Switching/Routing :: C3750 - Packets Lost
Nov 21, 2011I have a stack of 2 C3750-switches (WS-C3750G-24TS-1U) with IPBASE-firmware (12.2(52)SE).
When I ping to a machine (in this case a virtual one), the replies are always received on the port where the machine is connected, but on the port-channel connecting to the stack of the 'pinging device' the reply comes only for certain initiators, and not for all.
Setting:
Gi1/0/6: Device/Server I want to connect too ; defined as access port
Gi1/0/25 + Gi2/0/25, as Port-Channel 1: The location of the devices I connect (read as: the uplink to the stack of the PC's), defined for Dot1Q-trunking
Monitoring setup: Source ports: Both: Gi 1/0/6, Po1 (or Po1 replaced by both interfaces)
For the machines which can ping the server I see 2 echo (ping) requests, followed by 2 echo (ping) replies ... So once seen on the Po1, and once seen on the interface Gi1/0/6.
However for other machines, the 2nd reply is missing ; which must be caused by the dropping of these packets in the switch. At least, I my opinion this must be the reason... But I can't see any (change of) output drops at int Po1, nor at Gi1/0/6. The CPU doesn't seem to have high usage, and even then, I don't think the error would be constant, as it's always failing for some PC's, and never for others... (at least for a certain time, a few hours it can be constant, the problem dissapears from time to time).
