rewrite-rules (Interfaces)
Syntax
rewrite-rules {
dscp (rewrite-name | default) protocol (inet-both | inet-outer | mpls);
dscp-ipv6 (rewrite-name | default) protocol mpls;
exp (rewrite-name | default) protocol protocol-types;
exp-push-push-push default;
exp-swap-push-push default;
ieee-802.1 (rewrite-name | default) vlan-tag (outer | outer-and-inner);
ieee-802.1ad (rewrite-name | default) vlan-tag (outer | outer-and-inner);
inet-precedence (rewrite-name | default) protocol (inet-both | inet-outer | mpls);
}
Hierarchy Level
[edit class-of-service interfaces interface-name], [edit class-of-service interfaces interface-name unit logical-unit-number]
Description
Associate a rewrite-rules configuration or default mapping with a specific interface.
The [edit class-of-service interfaces interface-name unit
logical-unit-number] hierarchy level is not
supported on ACX Series routers.
Integrated
Bridging and Routing (IRB) interfaces are used to tie together Layer 2 switched and
Layer 3 routed domains on MX routers. MX routers support classifiers and rewrite
rules on the IRB interface at the [edit class-of-service interfaces irb unit
logical-unit-number] level of the hierarchy. All types of classifiers
and rewrite rules are allowed, including IEEE 802.1p.
The IRB classifiers and rewrite rules are used only for routed packets; in other words, it is for traffic that originated in the Layer 2 domain and is then routed through IRB into the Layer 3 domain, or vice versa. Only IEEE classifiers and IEEE rewrite rules are allowed for pure Layer 2 interfaces within a bridge domain.
On an MX Series router and on an EX Series switch,
exp-push-push-push, exp-swap-push-push, and
frame-relay-de are not supported on an integrated routing and
bridging (IRB) interface.
On an ACX Series router, only the outer tag is supported for dscp,
inet-precedence, and ieee802.1.
For IQ PICs, you can configure only one IEEE 802.1 rewrite rule on a physical port. All logical ports (units) on that physical port should apply the same IEEE 802.1 rewrite rule.
Options

rewrite-rules mapping configured at the [edit
class-of-service rewrite-rules] hierarchy level.
default—The default mapping.
The remaining statements are explained separately. See CLI Explorer.
Required Privilege Level
