how to copy the confi from 2900 series to another one

I know we can use copy & Paste, my Cisco 2921 price    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? More details, pls

•1.       Before that, do I need to wipe out the existing confi on the brand new switch?
     Answer:  I always ersase the default configuration on the switch by doing "er startup" and then reloading the 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? More details, pls
     Answer: Multiple ways you can use test network, you can assign it a static IP on the network and move the config from the other switch to this one or let it grab an IP from the DHCP and then move the config from the other switch to this one.  You can simply setup the other switch you are replacing as a tftp server to copy the config  Cisco 2951 price   to the new

3560 switches, differences

I have been looking at deploying a small core switch design for an important branch office that would consist of 2 cores with an etherchannel link and then 4 POE access switches linked to both cores utilising STP. I will also want static IP routing on the cores and will set up HSRP for gateway failover.

The initial switch I looked at for the core was WS-C3560X-24T-L    however after finding that there is no stock around of this at the moment I have seen the WS-C3560X-24T-S which looks like it will do everything I need including IP routing, HSRP and QoS for VOIP. The thing that concerns me is this is about £1000 cheaper so i'm slightly worried im missing someting. Any help in identifying this would be much apprciated?

First of all 3560E are end of life and the 3560X is the replacement for it so you should go for it. Don't believe you will have any feature shortcomings.

Basically I understand 3560X are an evolution of 3560E  switches. But they have some modularity. 3560X you won't  have gigabit  or 10gigabit uplinks unless you order them if you need to. 3560E came  with fixed 10gigabit uplinks.
I also read somewhere that 3560X are more energy efficient.

From 3560X Q&A 2nd question:

Q. What is new in the Cisco Catalyst 3750-X and 3560-X Series Switches?
A. The Cisco Catalyst X-Series switches build on the E-Series switches and add the following features:
• Cisco StackPower™  technology, available only on the Cisco Catalyst 3750-X (requires IP  Base), manages power very efficiently by aggregating and sharing power  supplies across a stack of switches. It also supports a feature known as  Zero-Footprint RPS.
• Field-replaceable network module provides 4 x 1 Gigabit and 2 x 10 Gigabit uplink interfaces for the switch.
• Full 802.3at PoE+ support provides 30W per port on all 48 ports in a single rack unit (RU) switch.
• New LAN Base feature set offers comprehensive Layer 2 functionality.
• Dual redundant power supplies and fans:  Four high-efficiency power supply options are available, including a DC  power supply for PoE applications. Two redundant, field-replaceable fan  modules are also included.
• MACsec  provides hardware-based encryption (802.1ae) at line rate on all 48  ports (requires IP Base) WS-C3560X-24T-S    . Includes MACsec Key Agreement (MKA) (included  in Dot1X-rev).

3750 vlan interface

Is there way to WS-C3750V2-24TS-S   create a vlan interface that wouldn't be routed, like on a layer 2 switch ?

I'd like to use this interface on a layer 2 isolated network, only to managed the c3750 by ssh.

sorry, I wasn't clear about the deploment :

Vlan252                10.114.252.254  YES NVRAM  up                    down

with the "ip routing" activated

So there's a route created automatically for the vlan interfaces/subnet :

     10.0.0.0/24 is subnetted, 6 subnets

C       10.114.10.0 is directly connected, Vlan10

C       10.114.11.0 is directly connected, Vlan11

C       10.114.12.0 is directly connected, Vlan12

C       10.114.1.0 is directly connected, Vlan2

C       10.114.250.0 is directly connected, Vlan250

C       10.114.253.0 is directly connected, Vlan1

S*   0.0.0.0/0 [1/0] via 10.114.250.1

I'd like to create an interface vlan 254 with an ip address that would not appear in the routing table.

I don't want the subnet of vlan 254 to be routed by the c3750 stack.

The global routing table will contain all the routes.  If you want to have a separate routing table for your management only, then you need to create a VRF and put your management vlan in that VRF.  This  WS-C3750X-48T-S   way you have complete separations between global and VRF tables.

Ok, Herman.  Can you post the output to the following commands:

1.  sh switch WS-C3750X-24P-S   detail; and

2.  sh version

Uplinking a Cisco 3560 Switch

I am fairly new to switching so I am just doing this in a test environment to teach myself some things. I am trying to uplink a cisco 3560 switch from another WS-C3560X-24T-L  switch. I have it linked and I can plug in a laptop to the switch and get out to the internet but I am unable to ping the switch, telnet, or ping from the switch. It shows that VLAN2 is down but I am not sure why. I have VLAN1 administratively down and should be using VLAN2.

The uplink port is configured like this:

 switchport trunk encapsulation dot1q

 switchport mode trunk

 srr-queue bandwidth share 10 10 60 20

 srr-queue bandwidth shape 10 0 0 0

 queue-set 2

 mls qos trust cos

 auto qos voip trust

The port that it is being uplinked from is configured like this:

 switchport trunk encapsulation dot1q

 switchport mode trunk

 I meant to say spare3.

Only do "sh vtp password" on the main WS-C3560X-24T-S   switch to see if there's any password setup.

avaya ip office with Catalyst 3560

I have the following config for my switch

int gig0/1  through int gig0/20

WS-C3560X-48PF-S   switchport access vlan 10

  switchport voice vlan 20

The Avaya IP Office (PBX)  is doing the dhcp for the voip. vlan 10 has 10.10.40.0/24 subnet. vlan 20 has 10.10.45.0/24 subnet. My PCs are connected via the VoIP. The issue that I am having is I cannot ping the pbx from any of the PC. I can see its MAC address in the CAM table, Ip routing is enabled.

Each of the VLANs need to have an IP address configured (from the correct rage).

Also, the PCs needs to be set to have their default gateway pointing to the IP address of the switch.

Also, the PBX needs to have its default gateway pointing to the Cisco (or at least a static route for 10.10.40/24 with next hop being the cisco WS-C3560X-48PF-L).

You can check your set up on the switch with the "show ip route" command, to make sure it does have the relevant routes - once you have IP addresses in each VLAN.

Can you post a sanitized config from the switch?  Can the switch ping the VLAN default gateways and the PBX?

cisco catalyst and cisco sbs with vlan

I have a cisco WS-C3560V2-24TS-S catalyst that i use as my gateway device. I also have a cisco sbs in the mix as well. Right now everything is working just fine. One cool thing i can do on the catalyst is create a single port interface assign to vlan 15. When i try the same thing on the cisco sbs using the gui it does not work at all. The SBS is allowing trunk access as i am able to hit all 3 of my VLANS.
I want to connect to the sbs on port 10 and assign my local network address to be 192.168.15.x  Any idea how i can do that.

!You can only have one active vlan interface on a layer 2 cisco WS-C3560V2-48TS-S switch. If you want to use an interface vlan 15 on the SG switch you will have to shut down the interface vlan 1 after creating the interface vlan 15. Then you should be able to connect to the sg 200 on that new interface.
