We need to implement VLANs on my company's network. I have 3750 L3 swtich, ive setup 3 vlans for testing. ive setup SVI everything.now how do I connect it to 3com that will also use VLANs. should I set trunk port of cisco and 3com? or no need?

View 6 Replies View RelatedI know we can use copy & Paste, my questions are:
1. Before that, do I need to wipe out the existing confi on the brand new switch?
2. About using TFTP, how does this new switch connects to the TFTP? Does it mean I have to assign a real IP and put it on our network?
For intervlan routing, Is 'IP routing' command enabled by default on a 6500 series switches based on the IOS?and on 3750 switches, do we need to enable the "ip routing" command manually for intervlan routing?

I am connecting power cable (series power cables) on 3750 stacks. i have connected them the same way the stack cables are connected i.e. fo rexample on a stack with 3 3750s:
1- fitst slot on fist switch connected the second slot last switch in the stack.
2- second slot/ port on the first switch to the first on second and seoncd on teh second switch to first on the third switch.
this how they are alway been stacked.Now, I need to connect power cables and I have followed the same method for stacks up to 4 switches. it seems that if a stack has more tham 4 switches, then the cabling will be dofferent!?I was wondering what will be on the cabling scheme for stacks more than 4 switches.

View 4 Replies View RelatedI'm thinking about using a 3750 stacking around 4 or 5 switches intead of using one 4500 series switch.
1-My first argument was concerning the budget (one 4500 instead of four or five 3750 in stack mode) ---- Here i think 4 or 5 stacked 3750 is cheap than one 4500
2- My second argument was about harware redundancing that i don't have with one 4500 and that i have with stack mode ----Here i have more hardware redundancing with 3750
3- The bug that we notice today in 2960 and 3750 and not in 4500

I want to limit the bandwidth of my Catalyst 3750 series switch, I read the cisco documentation and I applied the commands but I didn't get the wanted results.

I have a new Cisco 2960 S series switch with a basic configuration that needs to be uplinked or daisy chained to a Cisco 3750 switch. I am not getting any connectivity to the network with either a straight through or crossover cable. the port remains in amber but a 'show interface' indicates that the interface is up. I can manage the switch with a PC patched into any port on the switch with a static IP address. Must be something very simple that I am missing. Outlined below is the configuration.

I am trying to trunk between a 3Com 4800g and a Cisco 3500xl. I can get the a PC that connects to a vlan 1 port on thecisco switch to connect to the 3com switch and get connectivity. However, I cannot get anthing on the cisco switch that is on vlan 2 to connect and get dhcp. I am not a 3com guy, so I am not familiar with the command and configs.We have 2 vlans on both switches: Vlan 1 is Admin and Vlan 2 is Student.

I have 2 5500g 3com switches connected with 2 links. If LACP is disable, this causes serious problems and STP not works.
Logically , the link, is a port trunk with all the vlans permitted. One switch has STP enable and the other RSTP. Why this not works fine? I need to configure MSTP maybe? PVSTP is not allowed on this switches.

I am trying to use a SF302-08P switch to connect a conference phone (Cisco 7937) to my infrastructure. I connected the G2 port on the SF302 to a Gig copper port on the Catalyst. I configured both ports as trunked ports and port e1 on the SF302 as an access port for the phone. VLAN 1 is the default VLAN and VLAN 10 for voice. However, the phone does not connect to the Call Manager. I have changed the configurations on the G2 trunked port and the ethernet port (trunked ports, general ports, tagged and untagged). I have also changed the configuration on the Ethernet port (general, access, trunk, set it on the default VLAN, in the voice VLAN, etc.) The SF302 connects to the Catalyst, and PCs connect OK.

View 5 Replies View RelatedAt a customer i've tried to add a new 3750 switch til a running stack.I used the following proccess:
1. connect stack cables to the new switch
2. bootup new switch.
Normally the new switch will become a member of the stack, but here, the switch says its the stack master. I can see that the stack port from the old switches connecting the new is up.The only way i could make it work was to provisioning the new switch as switch nr x, save, power off and then connect it and boot it up.The IOS i the same on all switches.
Cisco C2960S IOS:12.2(55)SE5
Cisco C3560X IOS: 12.2(55)SE3
The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
2960:
mls qos map policed-dscp 0 10 18 24 46 to 8
mls qos map cos-dscp 0 8 16 24 32 46 48 56
mls qos srr-queue output cos-map queue 1 threshold 3 4 5
mls qos srr-queue output cos-map queue 2 threshold 1 2
mls qos srr-queue output cos-map queue 2 threshold 2 3
mls qos srr-queue output cos-map queue 2 threshold 3 6 7
[code].....
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.
I have a few old 2600 routers (2621, different IOS's) which I'm now replacing for new one's from the 2900 series (2901, Version 15.1(4)M4).In my configuration I have two IP addresses in my LAN interface and I have HSRP configured within the secondary IP subnet range. It would be something like this:
interface GigabitEthernet0/1
ip address 172.x.x.x x.x.x.x secondary
ip address 10.z.z.z z.z.z.z
[Code].....
Now, in the new 2900 routers, my interface configuration hasn't changed however I can see that the hello packets are now sent with the source within the respective HSRP IP subnet so I had to edit my acl for that:
permit udp 172.x.x.x x.x.x.x host 224.0.0.2 eq 1985
Is there a way I can force the HSRP to work as it previously did in the old IOS's?
I have a 2900 router at branch office. This router has a 4 port switch card and two gigabyte ports. The gigabyte port is use for wan connection and the 4 port switch card is use for lan connection. I have two separate networks on my lan side. (network 1 and network 2)
I have assigned port 0,1 of the switch card to vlan1 for network 1 Ports 2,3 of the switch card is assigned vlan 20 for network 2
My problem is I would like to applied a bandwidth restriction for all data coming out from vlan20 capping same to 384 kb.
Note I do not want use QOS because this will only kickin when saturation occurs,
