HP 5820 (JG219A) - Sub- Interface

Hi,

 

can anyone help?

 

I need to create a sub interface on HP 5820. However, it seems it´s not possible to create this interface:

 

HP Comware Platform Software
Comware Software, Version 5.20.105, Release 1808P12
HP A5820AF-24XG Switch with 2 Processors
1024M   bytes SDRAM
4M      bytes Nor Flash Memory
512M    bytes Nand Flash Memory
Config Register points to Nand Flash

Hardware Version is Ver.B
CPLDA Version is 002, CPLDB Version is 005
BootRom Version is 220
[SubSlot 0] 24SFP Plus+2GE Hardware Version is Ver.B

 

Desired Config:

ip vpn-instance app-vprn110

route-distinguisher 192.168.0.1:1158

description 'VRF Up_HP_App_1'

#

ip vpn-instance oam-vprn10

route-distinguisher 192.168.0.25:1160

description 'VRF Up_HP_OAM_1'

#

interface GigabitEthernet0/0/2

port link-mode route

combo enable copper

#

interface GigabitEthernet0/0/2.1158

ip binding vpn-instance app-vprn110

ip address 192.168.0.2 255.255.255.252

#

interface GigabitEthernet0/0/2.1160

ip binding vpn-instance oam-vprn10

ip address 192.168.0.26 255.255.255.252

#

ip route-static vpn-instance app-vprn110 0.0.0.0 0 192.168.0.1

ip route-static vpn-instance oam-vprn10 0.0.0.0 0 192.168.0.25

#

 

Thanks,

Michael

Re: HP 5820 (JG219A) - Sub- Interface

As a start I would update to the 1809P02 firmware just to rule out any fixes in between the latest version (1809P02) and the one you currently run (1808P12):

 

https://h10145.www1.hp.com/Downloads/SoftwareReleases.aspx?ProductNumber=JG219A

 

Regarding sub-interface you mean to have two different (tagged) vlans on the same physical interface or that you need an additional ip set for a particular VLAN and what is the purpose in that case?

 

On the 5820 (JC102A) you define a sub-interface like:

 

>ip address x.x.x.x y.y.y.y sub

As far as I understand on routing level vlans are not really required or used.

 

However, what we have to do here is:

We have several subnets with tagged VLANs, e.g. APP = Application & OAM = Operation and Maintenance

APP has 1158 and OAM has 1160 as tag. Both shall be transported via the same uplink port on level 3.

The uplink port is considered to be the transport net. Transportnet will have to different ip´s.

We found a solution using VRF but this is not what we want. Creating sub- interfaces using the "sub" statement doesn´t give the possibility to attach the VLAN- ID of the transport net.

Maybe it´s not really necessary to have any tags on the transport net?

Re: HP 5820 (JG219A) - Sub- Interface

Here is how I would do that on a HP 5820 (JC102A):

 

#
vlan 1158
description APP
#
vlan 1160
description OAM
#
vlan 1234
description UPLINK
#
interface Vlan-interface1158
description APP
ip address x.x.x.x y.y.y.y
#
interface Vlan-interface1160
description OAM
ip address x.x.x.x y.y.y.y
#
interface Vlan-interface1234
description UPLINK
ip address x.x.x.x y.y.y.y
#
interface Ten-GigabitEthernet1/0/1
port link-mode bridge
description DOWNLINK
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 1158 1160
port trunk pvid vlan 3101
undo jumboframe enable
#
interface Ten-GigabitEthernet1/0/24
port link-mode bridge
description UPLINK
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 1234
port trunk pvid vlan 3124
undo jumboframe enable
#
ip route-static 0.0.0.0 0.0.0.0 Vlan-interface1234 x.x.x.x permanent


In the above example VLAN1158 and 1160 is put as tagged on downlink and VLAN1234 is put as tagged on uplink.

Thanks for the info. Somehow like this is what we did by now.

However, isn´t trunk or bridge, as well as vlans layer 2?

We were asked to make the port a routing port...

 

By the way, the above example is from the HP simulator.

Well either you use "port link-mode bridge" along with vlans or "port link-mode route" and no vlans.

 

I prefer the first method, better granularity. The second method is perhaps more foolproof against L2-loops (like with VLAN you can cause a loop if you setup the same VLAN on 2 or more physical interfaces).

Hi.

When you use a bridge interface you also utilize spanning tree protocol (STP) if enabled.

A route interface does not utilize STP.

Usually in comware you can access the sub interface configuration but specifing it with a dot.

First you should set the parent (physical) interface in route mode then you can access the sub interface

#

interface ten 1/0/2.1186

ip addess 10.11..12.254 24

description GW for VLAN 1186.

#

Not sure if the exact hardware and firmware combination allows this, but this would be the general way to do this.

Re: HP 5820 (JG219A) - Sub- Interface

Dear sir,

 

here I am attaching my network daigram.

I have hp-5900 switches and i have created multiple vlan and interfaces like below

vlan 2   - int-vlan-2-ip -10.1.2.1

vlan 4- int-vlan-4-ip -10.1.4.1

vlan 6- int-vlan-6-ip- -10.1.6.1

I have server vlan -100, int-vlan100-10.1.100.1

my vlan are communicating to each other but i have to configure a virtual interfaces regardless of all respactive vlan so to communicate to each other for internet.

I want that if any client accesing my intranet vlan that is server (vlan 100), shouldnt go for router (dell sonic wall ) i mean it shoul route by hp-l3 switch when because of this lots latency is there
