NetScaler Snips to an interface without VLAN
That's right! Did you know that the NetScaler another method has to bind a SNIP IP address to an interface without an L3 (layer three) to create VLAN? Well, it is, so keep reading below how to learn.
Interestingly, the function which I will discuss in this blog post imported into NetScaler Firmware Release 10.0, but perhaps many of you who have provided the NetScaler in your area have never seen this feature in fact, and hence the reason for this particular post.
seenHistorically there have been two main methods to ensure that the traffic for a particular network determined / subnet on the NetScaler one would traverse desired interface:
- layer three VLAN - http: //support.citrix.com/article/CTX136926
- MBF (MAC based forwarding) - http://support.citrix.com/proddocs/topic/ns-system-10-map/ns-nw-interfaces-configrng-mac-bsd-frwrdng-tsk.html
I will not invest the time to explain the two methods mentioned above, considering that my focus for this post is this newer discuss and not so well-known method, a similar result is achieved.
[1945001Erledigen] the target with an ARP entry:You can bind the ARP entry by adding each of the following Snips in the example below, a special interface to a SNIP. This is to ensure that the response traffic will reach the same interface, through which the request was
Example Configuration Details .:
SNIP IP addresses: 10.10.10.2, 10.10.10.3, 10.10.10.4 and 10.10.10.5
MAC addresses for each of the respective interfaces ( find the MAC addresses for each of the NetScaler interfaces that can be found ' must'll want to bind a particular SNIP on). You can find the MAC address for each respective interface by logging into the NetScaler appliance and according to the example below:
> show interface 0/1
1) interface 0/1 (NetScaler Virtual Interface, PF 0 / 1) # 1
flags = 0xe060
MTU = 1500, native VLAN = 1, MAC = 52: 2c: 75: e4: 61: fc , uptime 118h08m42s
LLDP mode: none
RX: Pkts (5,350,740) bytes (1,514,302,712) errs (0) Drops (2351891) Stalls (0)
TX: Pkts (3,001,008 bytes) (844,999,742) Errs (0) drop (0) Stalls (0)
NIC: Indi (0) OutDisc (0) Fctls (0) Stalls (0 ) overhang (0) Steamed (0) [
bandwidth thresholds are not set
So, for this example we will use the following interfaces and related MAC addresses:
1/2 - 00: e0: ed: 0f bc: e0
1/3 - 00: e0: ed: 0f: bc: df
1/4 - 00: e0: ed: 0f bc: de
1/5 - 00: e0: ed: 1c: 89: 53
the following is a CLI (Command Line interface) example of how the four SNIP IP to bind addresses to the four NetScaler interfaces:
> Add arp 10.10.10.2 -ipAddress -mac 00: e0: ed: 0f bc: e0 -ifnum 1/2
Done
> Add arp 10.10.10.3 -ipAddress -mac 00: e0: ed: 0f: bc: df -ifnum 1/3
Done
> Add arp -ipAddress 10.10. 10.4 -mac 00: e0: ed: 0f bc: de -ifnum 1/4
Done
> Add arp 10.10.10.5 -ipAddress -mac 00: e0: ed: 1c: 89 : 53 -ifnum 1/5
Done
Summary:
So with a very simple configuration, you can bind SNIP use IP interface addresses without L3 VLAN
