Juniper EX3300, how to use snmp to get the mac address list

juniper

I am a network engineer at a middle network company,now we also use the traditional network architecture. While we deploy a new IDC point,we will meet the requite about how to identify a server with its mac-address,if we could get the mac list,I will work easy to make its vlan set.

I have done this with the network company HUAWEI, but I can't find the OID in Juniper,a very similar oid is "1.3.6.1.4.1.2636.3.40.1.5.1.4", but the result is the index number and the mac address, there was no number point to the interface number,so, any ideas?

The following is the part result about the command "snmpwalk -v2c -c XXX -Cc 1.1.1.1 1.3.6.1.4.1.2636.3.40.1.5.1.4"

Best Answer

If you still need this, and I understand what you are after, try the following:

show snmp mib walk 1.3.6.1.2.1.17.7.1.2.2

If that doesn't work, try this command and see if you can find the OID you are after:

show log snmp_reg_objs | match address

Router – How to change the ‘internal IP address’ of a Juniper SRX210H

While there is nothing wrong with Chopper's instructions per se, the SRX210 does not have a dedicate management interface. Out of the box, it will have port 0 configured as a WAN DHCP client, and all the rest of the ports as ethernet switching on VLAN0, and VLAN0 will have the IP 192.168.1.1. You'll want to login to J-Web, go to the configure tab, on the left side find VLANs and adjust theIP of the default VLAN. You may also need to adjust some other things like DHCP service pools to provide addresses on whatever subnet you change to. FYI.

Using the Juniper EX3300 Switch as a router

It is unclear whether you want topology A or B below (I think you need B, but your question seems to ask for A)

          Vlan10           Vlan10
A) [Users]----------[EX330]----------[ISP]
                   x.x.x.x/zz

          Vlan10           Vlan11
B) [Users]----------[EX330]---------------------------[ISP]
              y.y.y.y/24  xx.xx.xx.109/30     .110/30

A)
This is a flat layer2 vlan, and all your computers must be addressed on a subnet from the ISP. Vlan-10 is used for all your machines and they set their default-gateway to x.x.x.x.

I'm not sure why you're using a /32 mask in your question. It's unlikely that you want to do this, since it means you proxy-arp for all destinations. Work with your provider to understand what your actual netmask should be (I'm assuming zz, below)

delete interfaces ge-0/1/0 unit 0
delete interfaces ge-0/1/0
delete interfaces ge-0/1/1 unit 0
delete interfaces ge-0/1/1
set vlans vlan-10 vlan-id 10
set vlans vlan-10 interface ge-0/1/0
set vlans vlan-10 interface ge-0/1/1
set interfaces ge-0/1/0 unit 0 family ethernet-switching port-mode access
set interfaces ge-0/1/1 unit 0 family ethernet-switching port-mode access
set interfaces vlan unit 10 family inet address x.x.x.x/zz
set routing-options static route 0.0.0.0/0 next-hop xx.xx.xx.110

B)
This involves two different vlans: 10 and 11. Vlan-10 is used for all your servers and they set their default-gateway to y.y.y.y.

delete interfaces ge-0/1/0 unit 0
delete interfaces ge-0/1/0
delete interfaces ge-0/1/1 unit 0
delete interfaces ge-0/1/1
set vlans vlan-10 vlan-id 10
set vlans vlan-11 vlan-id 11
set vlans vlan-10 interface ge-0/1/0
set vlans vlan-11 interface ge-0/1/1
set interfaces ge-0/1/0 unit 0 family ethernet-switching port-mode access
set interfaces ge-0/1/1 unit 0 family ethernet-switching port-mode access
set interfaces vlan unit 11 family inet address xx.xx.xx.109/30
set interfaces vlan unit 10 family inet address y.y.y.y/zz
set routing-options static route 0.0.0.0/0 next-hop xx.xx.xx.110

Add as many ports as you need for servers in Vlan-11. Solution B must use some form of NAT if you don't have enough public address space from your provider to include both subnets for Vlan10 and Vlan11
