Linux IP ip addr (linux ip addr)

Clouddocs > > IP::addr Description¶Performs comparison of IP address/subnet/supernet to IPaddress/subnet/supernet, or parses 4 binary bytes into an IPv4 dottedquad addressSyntax¶IP::addr addr1>[/mask>] equals addr2>[/mask>]IP::addr parse [-swap] binary field> [offset>]IP::addr addr1> mask mask>v11 Additions/Changes:IP::addr parse [-ipv6|-ipv4 [-swap]] bytearray> [offset>]IP address comparison¶Performs comparison of IP address/subnet/supernet to IPaddress/subnet/supernet.Returns 0 if no match, 1 for a match.Use of IP::addr is not necessary if the class (v10+)or matchclass (v9) command is used to performthe address-to-address comparison.Does NOT perform a string comparison. To perform a literal stringcomparison, simply compare the 2 strings with the appropriate operator(equals, contains, starts_with, etc) rather than using the IP::addrcomparison.For versions 10.0 - 10.2.1, use the “slash notation” such as “/16” or“/24” instead of dotted decimal for the netmask like “/255.255.255.0”.The latter dotted decimal netmask notation passes iRule validation inversions 10.0 - 10.2.1, but does not reliably work. You can, however,specify the IP and mask as follows: “10.1.1.0 mask 255.255.255.0” (noslash at all with double quotes). The dotted decimal notation for / isrestored in version 10.2.2. (bug id 347628)IP address parsing (10.2.0-HF2 or higher only)¶Parses the value in into an IPv4 dotted quad address,starting at the given offset in bytes. The value of binaryfield must be 4 or more binary bytes intended to be parsed as an IPaddress. If the -swap option is specified, network byte orderconversion is performed on the bytes before parsing the address.Network ID Query¶Calculates the network ID of the given IP address and netmask for usein such constructs as switch statements.Route Domains¶The address parameter does not pick up the partition default RouteDomain. This is ID476920. When matching an address with a RouteDomain, the Route Domain must be specified.Examples¶To perform comparison of IP address 10.10.10.1 with subnet 10.0.0.0.(Will return 1, since it is a match.)[IP::addr 10.10.10.1 equals 10.0.0.0/8]To perform comparison of client-side IP address with subnet 10.0.0.0.(Will return 1 or 0, depending on client IP address.)[IP::addr [IP::client_addr]/8 equals 10.0.0.0][IP::addr "10.0.0.0 mask 255.0.0.0" equals [IP::client_addr]][IP::addr 10.42.2.0/24 equals 10.42.2.1]: 1[IP::addr 10.42.2.2 equals 10.42.2.0/24]: 1[IP::addr "10.42.2.0 mask 255.255.255.0" equals 10.42.2.1]: 1[IP::addr 10.42.2.2 equals "10.42.2.0 mask 255.255.255.0"]: 1To select a specific pool for a specific client IP address.when CLIENT_ACCEPTED { if { [IP::addr [IP::client_addr] equals 10.10.10.10] } { pool my_pool }}To perform a comparison of IP address 10.10.10.1 with a list ofaddresses in a Data Group List, use class (v10) ormatchclass (v9) instead:[class match 10.10.10.1 equals client_ip_class][matchclass 10.10.10.1 equals myIPs]To validate an IP address, you can use catch statement (by natty76)set a

understanding ip addr change and ip addr replace commands

A specific interface:If you want to display IP address for a specific interface for example ens3, type:ip address show ens3 You can replace ens3 with your available interface name.4. Add/Delete IP AddressesAdd IP Address to an interfacesudo ip addr 192.168.92.150/255.255.255.0 dev ens33or using CIDR notationsudo ip addr 192.168.92.150/24 dev ens33This add/assign the IP address 192.168.92.150 with a netmask of 255.255.255.0 to the network interface ens33. You can confirm by ip addr show ens33 command. The change is made immediately and no need to restart network service.Remember, adding IP this way is only temporary, ie on reboot it will be lost. To make permanent changes you need to edit the network configuration file, which depends on the specific Linux distribution and network manager you are using.If you use ip addr add to assign an IP address that the interface already has, the command will not produce an error, but it will not assign the IP address either because it’s already there. If it’s a new IP address it simply adds an additional IP address to the network interface. On that note to replace the current IP address, you should first delete the old one using ip addr del before adding the new one.Delete IP address from an interfacesudo ip addr del 192.168.92.150/24 dev ens33This command delete the IP address 192.168.92.150 from the ens33 network interface.Remember, If you are connected to the device over a network and you remove the IP address, your connection to the device will be lost. During server migration with a new subnet of IPs, we used to delete the existing IP address and add a new IP address in network config files. So when servers boot up in the new location it’s accessible using the new IP address (unless there are no network issues).4. Managing Network Interfaces

These steps to configure controller: Procedure Step 1 Configure AP to FlexConnect mode. Step 2 Create two WLAN SSID for the redundant radio links. Step 3 Configure CCKM. WGB Configuration For WGB fast secure roaming use case, it is recommended to configure CCKM and you need to configure CCKM on controller first. You are suggested to enable roaming coordinator when using DLEP. Follow these steps to configure WGB: Procedure Step 1 Configure DLEP neighbor under radio interface. Example: dlep neighbor 000c.29da.a804 rssi-threshold 72 cdr-threshold 120 where the MAC address is the interface MAC of ISR-G2. Step 2 Configure DLEP local port and server address under BVI1 or GigabitEthernet0 subinterface. Example: ip dlep local-port 38682 server-addr 100.100.1.2 server-port 55556 where the server address is the interface IP address of the ESR. Step 3 Configure CCKM. Example: dot11 ssid k901 vlan 901 authentication open eap EAP-FAST authentication network-eap EAP-FAST authentication key-management wpa version 2 cckm dot1x credentials FAST dot1x eap profile FASTeap profile FAST method fastdot1x credentials FAST username cisco password 0 ciscointerface Dot11Radio1 no ip address encryption mode ciphers aes-ccm encryption vlan 901 mode ciphers aes-ccm Step 4 Enable coordinator.

rp-address IP-ADDR - arubanetworking.hpe.com

Hello guys:I am trying to configure an iRule that performs load balancing based on the client IP. I need to load balance based on entire networks and based on some specific IP address. Those entire networks are 172.16.0.0/16, 172.17.0.0/16, 172.18.0.0/16, 192.168.20.0/24 and others. On the other hand, some specific client IPs are 172.17.0.20 (to be load balanced to pool_B), 192.168.20.10 (to be load balanced to pool_C) and others. Therefore, I guess I need to configure an iRule considering a data group so I can group all the nets and then, configure the LB lines to the specific client IPs. The iRule I wrote is:when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals My_NETS] } { pool pool_A snatpool snat_pool_A } elseif { [IP::addr [IP::client_addr] equals 172.17.0.20] } { pool pool_B snatpool snat_pool_B } elseif { [IP::addr [IP::client_addr] equals 192.168.20.10] } { pool pool_C snatpool snat_pool_C }}But I'm getting this error: 01070151:3: Rule [/Common/test] error: /Common/test:11: error: [undefined procedure: elseif][elseif { [class match [IP::client_addr] equals 172.17.0.20] } {I hope you could help me with this question.Thaks.What software version are you running? I wasn't able to reproduce the issue in v14.1.2.7. I imagine you're running into something like what's described in this other DevCentral post.You can try restructuring your iRule as follows to see if the error goes away:when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals My_NETS] } { pool pool_A snatpool snat_pool_A } elseif { [IP::addr [IP::client_addr] equals 172.17.0.20] } { pool pool_B snatpool snat_pool_B } elseif { [IP::addr [IP::client_addr]

Why ip addr, or other ip command not working any more? :

1. IntroductionThe ip command is a versatile tool in Linux for managing network configuration. It comes preinstalled in all modern Linux Distributions – part of the iproute2 package. This package replaces old tools such ifconfig, route etc. The ip command is commonly used to manage IP addresses, network interfaces, routes, ARP cache, and tunnels.In this guide, we learn about ip command in Linux in detail.2. ip Command SyntaxThe following shows the basic syntax of ip command:ip [OPTIONS] OBJECT {COMMAND | help}OPTIONS – This is optional to define global parameters or specific to a particular object (-s, -d, -r,-f -4, -6, up)OBJECT – For manipulation or viewing (like addr, link, route, neigh, maddr, tunnel)COMMAND – Action on the object ( like add, del, show, set, etc)ip command has a bit of complex syntax. It has many different objects and on top each object has its own options.The ip command requires sudo privilege when requires to change system network configurations such as adding or deleting IP addresses, routes, etc. However, elevated privileges are not required for basic operations such as listing IP addresses or network interfaces.3. Displaying IP AddressesYou can use ip command to display IP address associated with all network interfaces or on a specific interface.To display IP addresses for all interfaces:The following commands are used for the same purpose and give the same results.ip addr showThe output provides you a list of all the network interfaces (including the loopback interface) their associated IPv4 and IPv6 addresses alongside other information such as the maximum transmission unit (mtu) and transmit queue length (txqueuelen). The output includes other details like the broadcast address, subnet mask, and the current state of the interface (UP or DOWN).The commands ip address, ip addr and ip a will also show the same results.To display IP address for

The ping mpls command is useful for determining the number of output paths, but when the router is more than one hop away a router cannot always use those addresses to get the packet to transit through the router being interrogated. This situation exists because the change in the IP header destination address might cause the packet to be load-balanced differently by routers between the source router and the responding router. Load balancing is affected by the source address in the IP header. The following example tests load-balancing reporting from the upstream router: switch# ping mpls ipv4 10.131.161.251/32 ttl 1 repeat 1 dsmap hashkey ipv4 bitmap 8 Sending 1, 100-byte MPLS Echos to 10.131.161.251/32, timeout is 2 seconds, send interval is 0 msec: Codes: '!' - success, 'Q' - request not sent, '.' - timeout, 'L' - labeled output interface, 'B' - unlabeled output interface, 'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch, 'M' - malformed request, 'm' - unsupported tlvs, 'N' - no rx label, 'P' - no rx intf label prot, 'p' - premature termination of LSP, 'R' - transit router, 'X' - unknown return code, 'x' - return code 0 Type escape sequence to abort.

The following is sample output: Success rate is 0 percent (0/1) The following example shows a traceroute: switch# traceroute mpls ipv4 10.131.161.251/32 destination 127.0.0.6 ttl 2 Tracing MPLS Label Switched Path to 10.131.161.251/32, timeout is 2 seconds Codes: '!' - success, 'Q'
